mb/google/brya/var/agah: Update PEXVDD enable GPIO for next board rev
The next rev of this board will move the dGPU PEXVDD enable pin from
GPP_E10 to GPP_F12. This patch handles both the old and newer revisions
by using an ACPI Name to hold the GPIO # for PEXVDD enable. It also
cleans up the GPIO handling a little bit between board revs.
BUG=b:242752623
TEST=dGPU is functional and power sequencing tests still pass on board
rev 2
