johpow01 f19dc624a1 refactor(gpt): productize and refactor GPT library
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.

Zelalem Aweke 77c2775323 feat(rme): add RMM dispatcher (RMMD)
This patch introduces the RMM dispatcher into BL31. This
will be the mechanism that will enable communication to
take place between the Realm and non-secure world. Currently
gives the capability for granules to be
transitioned from non-secure type to realm and vice versa.
