mb/google/volteer: Implement touchscreen power sequencing
For touchscreens on volteer 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).
