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.
