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 Change-Id: I6c7815b81eb47fb41e58233fde512ac6b9c000a7 Signed-off-by: Tyler Wang <tyler.wang@quanta.corp-partner.google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/78254 Reviewed-by: Subrata Banik <subratabanik@google.com> Reviewed-by: Matt DeVillier <matt.devillier@gmail.com> Reviewed-by: Eric Lai <ericllai@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
