mb/goog/brya/var/brya0/skolas: Disable HPS GPIOs if HPS_ABSENT
Check FW_CONFIG and disable gpios for HPS if HPS_ABSENT for skolas
and brya0 variants.
BUG=b:311740746
BRANCH=firmware-brya-14505.B
TEST=`emerge-brya coreboot chromeos-bootimage`, flash and boot skolas
to kernel and verify via "cbmem -c | grep HPS".
