This patch stops including common_def.h from platform_def.h to
fix a circular depoendency between them.
This means platform_def.h now has to define the linker macros:
* PLATFORM_LINKER_FORMAT

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
component (TOS_FW_CONFIG_ID). It defines platform specific attributes
(memory range and physical CPU layout) as well as the attributes for
each secure partition (mostly load address). This manifest is passed
to the SPMC on boot up. An SP package contains the SP dtb in the SPCI
defined partition manifest format. As the SPMC manifest was enriched
it needs an increase of tos_fw-config max-size in fvp_fw_config dts.

This patch converts the 'plat_core_pos_by_mpidr' handler into an assembly

This patch disables the code to program reset vector for secondary
CPUs to a different entry point, than cold boot. The cold boot entry
point has the ability to differentiate between a cold boot and a warm
boot, that is controlled by the PROGRAMMABLE_RESET_ADDRESS macro. By
reusing the same entry point, we can lock the CPU reset vector during
cold boot.

Rather than creating entry in plat_arm_mmap array to map the
entire DRAM region in BL31/SP_MIN, only map a smaller region holding
HW_CONFIG DTB. Consequently, an increase in number of sub-translation
tables(level-2 and level-3) i.e., MAX_XLAT_TABLES is necessary to map
the new region in memory.
In order to accommodate the increased code size in BL31 i.e.,
PROGBITS, the max size of BL31 image is increased by 0x1000(4K).

The Raspberry Pi has two different UART devices pin-muxed to GPIO 14&15:
One ARM PL011 one and the 8250 compatible "Mini-UART".
A dtoverlay parameter in config.txt will tell the firmware to switch
between the two: it will setup the right clocks and will configure the
pinmuxes accordingly.
To autodetect the user's choice, we read the pinmux register and check
its setting: ALT5 (0x2) means the Mini-UART is used, ALT0 (0x4) points
to the PL011.
Based on that we select the UART driver to initialise.
This will allow console output in any case.

So far the Raspberry Pi 3 build needs the GPIO driver just for BL2.
Upcoming changes will require some GPIO code in BL1 and BL31 also, so
move those driver files into the common source section.
This does not affect BL31 code size at all, and bl1.bin just increases
by 144 bytes, but doesn't affect the padded binary size at all.

The Broadcom 283x SoCs feature multiple UARTs: the mostly used
"Mini-UART", which is an 8250 compatible IP, and at least one PL011.
While the 8250 is usually used for serial console purposes, it suffers
from a design flaw, where its clock depends on the VPU clock, which can
change at runtime. This will reliably mess up the baud rate.
To avoid this problem, people might choose to use the PL011 UART for
the serial console, which is pin-mux'ed to the very same GPIO pins.
This can be done by adding "miniuart-bt" to the "dtoverlay=" line in
config.txt.
To prepare for this situation, use the newly gained freedom of sharing
one console_t pointer across different UART drivers, to introduce the
option of choosing the PL011 for the console.
This is for now hard-coded to choose the Mini-UART by default.
A follow-up patch will introduce automatic detection.

There is really no reason to use and pass around a struct when its only
member is the (fixed) base address.
Remove the struct and just use the base address on its own inside the
GPIO driver. Then set the base address automatically.
This simplifies GPIO setup for users, which now don't need to deal with
zeroing a struct and setting the base address anymore.

Merge the previously introduced arm_fconf_io_storage into arm_io_storage. This
removes the duplicate io_policies and functions definition.
This patch:
- replace arm_io_storage.c with the content of arm_fconf_io_storage.c
- rename the USE_FCONF_BASED_IO option into ARM_IO_IN_DTB.
- 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
of fvp stays the same as it was before the introduction of fconf.
