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
