mb/amd/(birman|mayan): Update chromeos.fmd files

Because the EFS is now fixed at 0xff020000, the ChromeOS RO region needs
to be moved to the bottom of the ROM area to cover that space.

The RO Region 6MiB, but you can't actually set 6MiB as RO - it's either
4 or 8MiB, so that's adjusted.  To leave some room for the RW_LEGACY
region, the two RW regions are adjusted to 3MiB each, which should be
plenty.

The GBB region had to be moved from the front of the WP_RO region to the
end to avoid conflicting with the EFS, which needs to be inside the
coreboot cbfs area.

Also get rid of AMD_FWM_POSITION_INDEX.  The FWM position is no longer
needed.
