mb/google/myst: Re-organize the FMAP layout
By moving certain FW UI assets from RO to RW sections, 4 MiB is
sufficient for RO section. Split the resultant available 4 MiB equally
between 2 RW sections. This will help in getting to 16 MiB SPI flash for
the mainboard.
BUG=b:281567816
TEST=Build Myst BIOS image with the updated layout.
