mainboard/google/reef: adjust chromeos.fmd regions
- Drastically reduced RW_MRC_CACHE size to hold one update. Now
that this area isn't changing after every S5 entry there's no
need make it so large.
- ELOG area reduced by 4KiB for subsequent area alignment. In practice
this doesn't matter because the elog library only uses 4KiB bytes.
16KiB->12KiB is a nop.
- Moved RW_NVRAM for subsequent alignment.
- Most importantly, RW_SECTION_(A|B) are aligned to 64KiB boundaries
and sized to 64KiB multiples. This ensures updates don't need a
read-modify-write that could force a system into recovery if
an inopportune power event occurred.
