Snow: Set up the ChromeOS GPIOs as inputs during the ROM stage.
We need these to be inputs so they can be read when populating the coreboot
tables. It seems like a good idea to do this early to ensure that the input
gate capacitance has had a chance to charge, and if we decide to use
actually use that information during the ROM stage to do earlier RW
firmware selection.
It is not guarded by a ChromeOS config variable because those lines are
always intended to be input GPIOs, regardless of whether we're running
ChromeOS or not.
