mb/google/zork: Reorganize chromeos.fmd to increase WP_RO to 8MiB
This change reorganizes flash map layout for zork to allow WP_RO to
grow to 8MiB. This is to allow more space for the firmware UI screens
in RO. Following changes are made in the layout:
1. MRC_CACHE_HOLE is dropped since only one slot of 64K is used for
MRC cache. Next section can start on 64K boundary immediately after
MRC cache.
2. RW_SECTION_A and RW_SECTION_B are dropped down in size to 3MiB
each. Each region is currently at ~2MiB of usage.
3. RW_ELOG is restrictred to 4KiB as that is the maximum elog size
supported by coreboot.
4. SMMSTORE is restricted to 4K.
5. RW_LEGACY region is dropped down to ~1.9MiB.
BUG=b:161949925
TEST=Verified that write-protection for RO still works fine, device
boots in recovery and non-recovery mode. Also, verified that the dump
of fmap looks correct:
dump_fmap -h firmware/image-trembyle.serial.bin
