Currently, console drivers prepend '\r' to '\n' by themselves. This is
common enough to be supported in the framework.
Add a new flag, CONSOLE_FLAG_TRANSLATE_CRLF. A driver can set this
flag to ask the framework to transform LF into CRLF instead of doing
it by itself.

NOTE: __ASSEMBLY__ macro is now deprecated in favor of __ASSEMBLER__.
All common C compilers predefine a macro called __ASSEMBLER__ when
preprocessing a .S file. There is no reason for TF-A to define it's own
__ASSEMBLY__ macro for this purpose instead. To unify code with the
export headers (which use __ASSEMBLER__ to avoid one extra dependency),
let's deprecate __ASSEMBLY__ and switch the code base over to the
predefined standard.

Code using Cryptocell specific APIs was used as part of the
arm common board ROT support, instead of being abstracted
in Cryptocell specific driver code, creating two problems:
- Any none arm board that uses Cryptocell wuld need to
copy and paste the same code.
- Inability to cleanly support multiple versions of Cryptocell
API and products.
Move over Cryptocell specific API calls into the Cryptocell
driver, creating abstraction API where needed.

This patch adds a new include/export/ directory meant for inclusion in
third-party code. This is useful for cases where third-party code needs
to interact with TF-A interfaces and data structures (such as a custom
BL2-implementation like coreboot handing off to BL31). Directly
including headers from the TF-A repository avoids having to duplicate
all these definitions (and risk them going stale), but with the current
header structure this is not possible because handoff API definitions
are too deeply intertwined with other TF code/headers and chain-include
other headers that will not be available in the other environment.
The new approach aims to solve this by separating only the parts that
are really needed into these special headers that are self-contained and
will not chain-include other (non-export) headers. TF-A code should
never include them directly but should instead always include the
respective wrapper header, which will include the required prerequisites
(like <stdint.h>) before including the export header. Third-party code
can include the export headers via its own wrappers that make sure the
necessary definitions are available in whatever way that environment can
provide them.

Rework the macro that eases the table definition: the src and msk fields
are now using MASK and SHIFT defines of each source register.
Some macros had then to be modified: _USART1_SEL, _ASS_SEL and _MSS_SEL to
_UART1_SEL, _AXIS_SEL, and _MCUS_SEL to match register fields.
Note: the mask for RCC_ASSCKSELR_AXISSRC is changed from 0x3 to 0x7
to reflect the size of the register field, even if there are only
3 possible clock sources.
The mask value is also corrected for QSPI and FMC clock selection.

The chain of trust description and the pointer pointing to its first
element were incompatible, thus requiring an explicit type cast for
the assignment.
- cot_desc was an array of
const pointers to const image descriptors.
- cot_desc_ptr was a const pointer to
(non-constant) pointers to const image descriptors.
Thus, trying to assign cot_desc to cot_desc_ptr (with no cast) would
generate the following compiler warning:
drivers/auth/tbbr/tbbr_cot.c:826:14: warning: initialization discards
‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
REGISTER_COT(cot_desc);

This changes the auth_img_desc_t struct to have pointers to struct
arrays instead of struct arrays. This saves memory as many of these
were never used, and can be NULL pointers. Note the memory savings are
only when these arrays are not initialised, as it is assumed these
arrays are fixed length. A possible future optimisation could allow for
variable length.

When Trusted Board Boot is enabled, we need to specify the Chain of
Trust (CoT) of the BL1 and BL2 images. A CoT consists of an array
of image descriptors. The authentication module assumes that each
image descriptor in this array is indexed by its unique image
identifier. For example, the Trusted Boot Firmware Certificate has to
be at index [TRUSTED_BOOT_FW_CERT_ID].
Unique image identifiers may not necessarily be consecutive. Also,
a given BL image might not use all image descriptors. For example, BL1
does not need any of the descriptors related to BL31. As a result, the
CoT array might contain holes, which unnecessarily takes up space in
the BL binary.
Using pointers to auth_img_desc_t structs (rather than structs
themselves) means these unused elements only use 1 pointer worth of
space, rather than one struct worth of space. This patch also changes
the code which accesses this array to reflect the change to pointers.
Image descriptors not needed in BL1 or BL2 respectively are also
ifdef'd out in this patch. For example, verifying the BL31 image is
the responsibility of BL2 so BL1 does not need any of the data
structures describing BL31.

Valid addresses for GICR base are always a set calculable distance from
the GICD and is based on the number of cores a given instance of GICv3 IP
can support. The formula for the number of address bits is given by the
ARM GIC-500 TRM section 3.2 as 2^(18+log2(cores)) with the MSB set to
one for GICR instances. Holes in the GIC address space are also
guaranteed to safely return 0 on reads. This allows us to support runtime
detection of the GICR base address by starting from GIC base address plus
BIT(18) and walking until the GICR ID register (IIDR) is detected. We
stop searching after BIT(20) to prevent searching out into space if
something goes wrong. This can be extended out if we ever have a device
with 16 or more cores.
