mainboard/google/poppy: Add PowerResource for touchscreen device
1. Do not enable touchscreen device by default in gpio configuration.
2. Select use of PowerResource for touchscreen device in devicetree so
that the ACPI subsystem can take care of powering on/off the
device. When system enters suspend, touchscreen device is powered off
and on resume, it is powered back on.
BUG=b:62028489
TEST=Verified 100 cycles of suspend-resume. Touchscreen still works on
poppy.
