mb/google/rex/var/karis: Set touchscreen power/reset GPIOs correctly
The tochscreen isn't powered on yet when the detection is done, it
makes touchscren no function.
Set touchscreen power and reset GPIOs correctly in romstage and
ramstage to make the detect feature works.
BUG=b:303130400
TEST=(1) emerge-rex coreboot
(2) Test on karis, touchscreen function works
