Yanfeng Liu 102a62c7e3 mm/mm_gran: remove allocation size limitation
This patch refactors granule allocator to remove the 32 granules
limitation with the help of a gran_range_s structure and related
functions, see "mm_grantable.h" for details.

Below are the major functions explaining how this works:

- The gran_match() checks if a gran range all in the given state.
  it gives last mismatch position when fails free range matching.
- The gran_search() tries to find the position of a free range.
  It leverages last mismatch position from gran_match() to speed
  up the search.

range size handling is mainly in gran_match() and gran_set_().
