soc/amd/common/graphics: Update VBIOS cache data before hashing

On the first boot after flashing, the data read from the FMAP and
stored in vbios_data is not valid, so hashing it produces a value which
will not match on the subsequent boot, requiring an additional boot
before the vbios_data and hash match / before the GOP driver can be
skipped. To fix this, update vbios_data before hashing.

BUG=b:271850970
BRANCH=skyrim
TEST=build/boot google/skyrim with USE_SELECTIVE_GOP_INIT selected,
verify that GOP driver execution is skipping on 2nd boot after flashing
when booting in normal / verified boot mode.
