Add the new routine ps3_mm_set_repository_highmem() that saves highmem info to
the ps3 repository. Also, move the existing ps3_mm_get_repository_highmem()
routine up in the source file.
This inplementation of ps3_mm_set_repository_highmem() assumes the repository
will have a single highmem region entry (at index 0).
