mb/google/zork: Fix Goodix touchscreen ACPI node
This change does the following: a. USI_REPORT_EN is no longer set to high in coreboot. Instead GPIO_144 is exposed as stop_gpio in ACPI to allow OS to control this pad as required. b. Appropriate delays are added for power-down sequencing: - Delay after REPORT_EN is disabled - 1ms - Delay after RESET is asserted - 1ms BUG=b:159501288 Signed-off-by: Furquan Shaikh <furquan@google.com> Change-Id: If4d12fa0d4f4e5123d8fdccdabda996dcafa4523 Reviewed-on: https://review.coreboot.org/c/coreboot/+/43701 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Felix Held <felix-coreboot@felixheld.de> Reviewed-by: Aaron Durbin <adurbin@chromium.org>
