feat(plat/arm): add GPT parser support
Added GPT parser support in BL2 for Arm platforms to get the entry
address and length of the FIP in the GPT image.
Also, increased BL2 maximum size for FVP platform to successfully
compile ROM-enabled build with this change.
Verified this change using a patch:
