mb/google/octopus: Implement touchscreen/digitizer power sequencing
For octopus variants with a touchscreen/digitizer, drive the enable and
reset GPIOs high in romstage, then disable the reset GPIOs in ramstage.
Where available, only set the GPIOs for SKUs which have a touchscreen.
This will allow coreboot to detect the presence of i2c touchscreens
during ACPI SSDT generation (implemented in a subsequent commit).
TEST=tested with rest of patch train
