mb/goog/brya/var/brya0/skolas: Disable LTE GPIOs if LTE_ABSENT
Check FW_CONFIG and disable gpios for LTE if LTE_ABSENT for skolas
and brya0 variants.
BUG=b:311459627
BRANCH=firmware-brya-14505.B
TEST=`emerge-brya coreboot chromeos-bootimage`, flash and boot skolas
to kernel and verify LTE gpios are disabled via "cbmem -c | grep LTE".
