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".
