mb/google/hatch: Implement touchscreen power sequencing
For touchscreens on hatch variants, drive the enable GPIO high starting
in romstage, then disable the reset GPIO in ramstage. This will allow
coreboot to detect the presence of i2c touchscreens during ACPI SSDT
generation (implemented in a subsequent commit).
