mb/google/eve: Add power controls to touchscreen device
Instead of having the SMI handler power off the touchscreen on the
way into suspend add power resource controls to the ACPI device so
the power is managed by the kernel instead of the BIOS.
BUG=b:35581264
TEST=manual testing on Eve to ensure that the touchscreen is still
functional at boot and after suspend/resume, and that it does not
draw power in suspend.
