Initial version

Add some common FF-A functionality. Supported features (roughly):
  - define FF-A function IDs and error codes
  - create boot info descriptor
  - create partition info descriptor
  - create and parse memory transaction descriptor
  - parse memory relinquish descriptor
  - parse console log message

Limitations apply, code quality is not production ready.
