mb/google/kahlee: Disable touchscreen GPIO export in CRS 

Disable GPIO export in ACPI _CRS for touchscreens which set the
register "have_power_resource." This eliminates the error:
[ERROR]  I2C: <bus:addr>: Exposing GPIOs in Power Resource and _CRS

TEST=build/boot barla/liara, verify touchscreen functional, no error in
cbmem log.
