    google/reef: Update chromeos.fmd file
    
    1. Mark 256KiB at end of BIOS region as unusable BIOS region is
    memory-mapped just below 4GiB, however last 256KiB is unusable. Mark it
    accordingly in fmd file.
    2. Use up holes in RW region for RW_A and RW_B.
    3. Fill up holes in RO with UNUSED regions.
