mb/google/zork: Add touchscreen power control
This change adds support for touchscreen power control using:
* GPIO_90 for trembyle based boards
* GPIO_32 for dalboz based boards
By default, baseboard tables configure these GPIOs as PAD_GPO driven
low and override trees expose these pads as enable_gpio to be used by
ACPI power resource.
In order to support pre-v3.6 boards, override tables configure these
pads as PAD_NC and drop the enable_gpio setting from device tree based
on board version.
BUG=b:161935640, b:162747210
