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.

# Currently, it is required that the BIOS region be a multiple of 8KiB.
# This is required so that the recovery mechanism can find SIGN_CSE
# region aligned to 4K at the center of BIOS region. Since the
# descriptor at the beginning uses 4K and BIOS starts at an offset of
# 4K, a hole of 4K is created towards the end of the flash to compensate
# for the size requirement of BIOS region.
# FIT tool thus creates descriptor with following regions:
# Descriptor --> 0 to 4K
# BIOS --> 4K to 0xf7f000
# Device ext --> 0xf7f000 to 0xfff000
