mb/google/kahlee: Don't reset the touchpad/screen on boot
touchpad & touchscreen power enable gets reset during resume causing unintended wake interrupts, causing dark resume failures. This prevents the board from being shut down after it's been suspended for a long period of time and can end up draining the battery. BUG=b:153173717 TEST=Build only - Needs to be tested by ODMs. Signed-off-by: Martin Roth <martin@coreboot.org> Change-Id: If403da8853e59eaaf589062c9bd6f10deb626998 Reviewed-on: https://review.coreboot.org/c/coreboot/+/41063 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Kevin Chiu <Kevin.Chiu@quantatw.com>
