Definition of GUIDed HOB for reserving MMRAM regions.
This file defines:
* the GUID used to identify the GUID HOB for reserving MMRAM regions.
* the data structure of MMRAM descriptor to describe MMRAM candidate regions
* values of state of MMRAM candidate regions
* the GUID specific data structure of HOB for reserving MMRAM regions.
This GUIDed HOB can be used to convey the existence of the T-SEG reservation and H-SEG usage
