This patch updates and refactors the GPT library and fixes bugs. - Support all combinations of PGS, PPS, and L0GPTSZ parameters. - PPS and PGS are set at runtime, L0GPTSZ is read from GPCCR_EL3. - Use compiler definitions to simplify code. - Renaming functions to better suit intended uses. - MMU enabled before GPT APIs called. - Add comments to make function usage more clear in GPT library. - Added _rme suffix to file names to differentiate better from the GPT file system code. - Renamed gpt_defs.h to gpt_rme_private.h to better separate private and public code. - Renamed gpt_core.c to gpt_rme.c to better conform to TF-A precedent.
