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.
