feat(spmd): introduce FFA_PARTITION_INFO_GET_REGS
Add code in SPMD to forward calls to FFA_PARTITION_INFO_GET_REGS. This
is a new ABI that allows getting partition information without the need
for rx/tx buffer, that helps in situations where having an rx/tx buffer
mapped and available is difficult (ex. uefi runtime services).
Currently, the spmc at el3 does not support this new ABI.
The new ABI uses registers x8-x17 to return partition information so
changes are made to ensure those registers are passed through to the
SPMC and restored on the return path.

build: clarify linker script generation
The following build system variables have been renamed:
- `LINKERFILE` -> `DEFAULT_LINKER_SCRIPT`
- `BL_LINKERFILE` -> `DEFAULT_LINKER_SCRIPT_SOURCE`
- `<IMAGE>_LINKERFILE` -> `<IMAGE>_DEFAULT_LINKER_SCRIPT_SOURCE`
These new names better reflect how each variable is used:
1. the default linker script is passed via `-dT` instead of `-T`
2. linker script source files are first preprocessed
Additionally, linker scripts are now placed in the build directory
relative to where they exist in the source directory. For example,
the `bl32/sp_min/sp_min.ld.S` would now preprocess to
`sp_min/sp_min.ld` instead of just `bl32.ld`
BREAKING-CHANGE: The `LINKERFILE`, `BL_LINKERFILE` and
`<IMAGE_LINKERFILE>` build system variables have been renamed. See the
commit message for more information.

feat(spmd): copy tos_fw_config in secure region
The tos_fw_config is currently loaded into memory by BL2 and
consumed by SPMD (part of BL31) and BL32 firmwares. This does
not work in RME-enabled systems as BL31 uses the root PAS memory
and does not trust secure PAS memory.
A first attempt was made to map the TOS_FW_CONFIG region as root PAS,
and then to remap to secure PAS after SPMD consumption, but this was
not suitable for RME systems where memory encryption is enabled.
This can be solved by copying the TOS FW config (SPMC manifest) from
the Root PAS region to the Secure PAS region so that BL32 can consume
it.

feat(rme): set DRAM information in Boot Manifest platform data
This patch adds support for setting configuration of DRAM banks
for FVP model in RMM-EL3 Boot Manifest structure.
Structure 'rmm_manifest' is extended with 'plat_dram' structure
which contains information about platform's DRAM layout:
- number of DRAM banks;
- pointer to 'dram_bank[]' array;
- check sum: two's complement 64-bit value of the sum of
data in 'plat_dram' and 'dram_bank[] array.
Each 'dram_bank' structure holds information about DRAM
bank base address and its size. This values must be aligned
to 4KB page size.
The patch increases Boot Manifest minor version to 2 and
removes 'typedef rmm_manifest_t' as per
"3.4.15.1. Avoid anonymous typedefs of structs/enums in headers" of

fix: unify fallthrough annotations
Compiling with -Wimplicit-fallthrough=3 (enabled by -Wextra) produces
many warnings about fallthrough comments either missing or being wrong.
Unify the comments so we comply with -Wextra.
Note that Coverity recommends against using the __attribute__ directive.
Also, zlib does not build with a higher value of -Wimplicit-fallthrough.
Finally, compilers strip comments before expanding macros. As such,
checkpatch's fallthrough annotation (or higher levels of the flag) isn't
really possible.
