mb/google/octopus: Add method to set GPIOs in romstage

Add method variant_romstage_gpio_table() with empty weak implementation
to allow variants to override as needed for touchscreen power
sequencing (to be implemented in a subsequent commit). Call method
in romstage to program any GPIOs the variant may need to set.

TEST=tested with rest of patch train
