mb/google/zork/ezkinil: Fix ELAN touchscreen ACPI node

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. Add Delay after stop_gpio Low - 300ms

Shouldn't we have 'register generic. […]

Yes, we need generic.disable_gpio_export_in_crs as well.

Does this delay of 300ms match the spec?

I see from the bug that the 300ms is the recommended delay. Just a note that this 300ms would result in adding delay to both boot and resume paths. Some other projects have been able to reduce this delay to 100ms (IIRC). So, it would be good to see if that is an option here.

Because EN_PWR_TOUCHSCREEN will be changed in schematic V3.61. We will re-measuring and test timing then modify this value on Ezkinil next build.
