As per "include/export/README", TF-A code should never include export
headers directly. Instead, it should include a wrapper header that
ensures the export header is included in the right manner.
"tbbr_img_def_exp.h" is directly included in TF-A code, this patch
replaces it with its wrapper header "tbbr_img_def.h".

The stdout-path property in the /chosen node of a DTB points to a device
node, which is used for boot console output.
On most (if not all) ARM based platforms this is the debug UART.
The ST platform code contains a function to parse this property and
chase down eventual aliases to learn the node offset of this UART node.
Introduce a slightly more generalised version of this ST platform function
in the generic fdt_wrappers code. This will be useful for other platforms
as well.

The STM32 platform port parse DT nodes to find base address to
peripherals. It does this by using its own implementation, even though
this functionality is generic and actually widely useful outside of the
STM32 code.
Re-implement fdt_get_reg_props_by_name() on top of the newly introduced
fdt_get_reg_props_by_index() function, and move it to fdt_wrapper.c.
This is removes the assumption that #address-cells and #size-cells are
always one.

At the moment the fconf_populate_gicv3_config() implementation is
somewhat incomplete: First it actually fails to store the retrieved
information (the local addr[] array is going nowhere), but also it makes
quite some assumptions about the device tree passed to it: it needs to
use two address-cells and two size-cells, and also requires all five
register regions to be specified, where actually only the first two
are mandatory according to the binding (and needed by our code).
Fix this by introducing a proper generic function to retrieve "reg"
property information from a DT node:
We retrieve the #address-cells and #size-cells properties from the
parent node, then use those to extract the right values from the "reg"
property. The function takes an index to select one region of a reg
property.
This is loosely based on the STM32 implementation using "reg-names",
which we will subsume in a follow-up patch.

Our fdtw_read_cells() implementation goes to great lengths to
sanity-check every parameter and result, but leaves a big hole open:
The size of the storage the value pointer points at needs to match the
number of cells given. This can't be easily checked at compile time,
since we lose the size information by using a void pointer.
Regardless the current usage of this function is somewhat wrong anyways,
since we use it on single-element, fixed-length properties only, for
which the DT binding specifies the size.
Typically we use those functions dealing with a number of cells in DT
context to deal with *dynamically* sized properties, which depend on
other properties (#size-cells, #clock-cells, ...), to specify the number
of cells needed.
Another problem with the current implementation is the use of
ambiguously sized types (uintptr_t, size_t) together with a certain
expectation about their size. In general there is no relation between
the length of a DT property and the bitness of the code that parses the
DTB: AArch64 code could encounter 32-bit addresses (where the physical
address space is limited to 4GB [1]), while AArch32 code could read
64-bit sized properties (/memory nodes on LPAE systems, [2]).
To make this more clear, fix the potential issues and also align more
with other DT users (Linux and U-Boot), introduce functions to explicitly
read uint32 and uint64 properties. As the other DT consumers, we do this
based on the generic "read array" function.
Convert all users to use either of those two new functions, and make
sure we never use a pointer to anything other than uint32_t or uint64_t
variables directly.
This reveals (and fixes) a bug in plat_spmd_manifest.c, where we write
4 bytes into a uint16_t variable (passed via a void pointer).
Also we change the implementation of the function to better align with
other libfdt users, by using the right types (fdt32_t) and common
variable names (*prop, prop_names).

Currently our fdtw_read_array() implementation requires the length of
the property to exactly match the requested size, which makes it less
flexible for parsing generic device trees.
Also the name is slightly misleading, since we treat the cells of the
array as 32 bit unsigned integers, performing the endianess conversion.
To fix those issues and align the code more with other DT users (Linux
kernel or U-Boot), rename the function to "fdt_read_uint32_array", and
relax the length check to only check if the property covers at least the
number of cells we request.
This also changes the variable names to be more in-line with other DT
users, and switches to the proper data types.
This makes this function more useful in later patches.

When using the SPM Dispatcher, the SPMC sits as a BL32 component
(BL32_IMAGE_ID). The SPMC manifest is passed as the TOS fw config

each secure partition (mostly load address). This manifest is passed

- use the ARM_IO_IN_DTB option to compile out io_policies moved in dtb.
- propagate DEFINES when parsing dts.
- use ARM_IO_IN_DTB to include or not uuid nodes in fw_config dtb.
- set the ARM_IO_IN_DTB to 0 by default for fvp. This ensure that the behavior

The motivation behind this patch and following patches is to extract
information about the platform in runtime rather than depending on
compile time macros such as FVP_CLUSTER_COUNT. This partially enables
us to use a single binary for a family of platforms which all have
similar hardware capabilities but differ in configurations.
we populate the data structure describing the power domain hierarchy
of the platform dynamically by querying the number of clusters and cpus
using fconf getter APIs. Compile time macro such as FVP_CLUSTER_COUNT
is still needed as it determines the size of related data structures.
Note that the cpu-map node in HW_CONFIG dts represents a logical
hierarchy of power domains of CPU. However, in reality, the power
domains may not have been physically built in such hierarchy.

fvp-base-gicv3-psci-dynamiq-common.dtsi
As this file includes fvp-base-gicv3-psci-common.dtsi, it is necessary
to delete all previous cluster node definitons because DynamIQ based
models have upto 8 CPUs in each cluster. If not deleted, the final dts
would have an inaccurate description of SoC topology, i.e., cluster0
with 8 or more core nodes and cluster1 with 4 core nodes.
