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) Change-Id: Ifdd75cd96e7b6880085a3f47214b92948a56aa2e Signed-off-by: Matt DeVillier <matt.devillier@amd.corp-partner.google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/69456 Reviewed-by: Angel Pons <th3fanbus@gmail.com> Reviewed-by: Martin Roth <martin.roth@amd.corp-partner.google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
