STOP API: API conditionally supports 255 SCOM restore entries for each quad.

This is first of the series of commits intended for incorporating
new mechanisms for SCOM restore. STOP API looks for a specific
version in QPMR header of HOMER. If version is greater than 2, it allows
 - 255 SCOM Restore entries per quad
 - doesn't divide quad restore region in to L2, L3 and EQ sub-region
If version is less than or equal to 2, API provideis legacy
functionality.
