mb/google/hatch: Bump up the BIOS region to 28MiB
This change bumps up the BIOS region to 28MiB to use the hole
between SI_ALL and SI_BIOS. Since this SPI flash part is 32MiB, only
the top 16MiB actually gets memory mapped. Thus, the change ensures
that only RW_LEGACY lies in the 12MiB that is not memory mapped.
BUG=b:123443737
TEST=Verified that hatch still boots up. Ensured that fmap dump looks
correct.
