mb/google/zork: Implement touchscreen power sequencing
As all variants have a touchscreen option, in baseboard tables set the
enable GPIO high and hold in reset during romstage, then release reset
in ramstage. This will allow the touchscreen to make use of the runtime
I2C detect feature (enabled in a subsequent commit) so that an ACPI
device entry is created only for the touchscreen actually present.
This mirrors the change to skyrim in commit f90ff456
(mb/google/skyrim: Implement touchscreen power sequencing)
