mb/google/octopus: Implement touchscreen, digitizer power sequencing

For touchscreens/digitizers on octopus variants, drive the enable
GPIO high starting in bootblock, then disable the reset GPIO in ramstage.
This will allow coreboot to detect the presence of i2c touchscreens/
digitizers during ACPI SSDT generation.
