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
https://trustedfirmware-a.readthedocs.io/en/latest/process/coding-style.html
