atlas: control touchscreen power using ACPI
This adds the ACPI controls for power sequencing the touchscreen.
The initial setting is to keep the touchscreen powered off and in
reset. When linux is ready to talk to the touchscreen, it powers it
on and releases reset via ACPI.
BUG=b:110286344
TEST=verified touchscreen is functional in chromeos
