Shawn Nematbakhsh 77ca452cd6 baytrail: Add GPIO initial configuration infrastructure. 
During ramstage, call mainboard_get_gpios to get initial GPIO configuration
from the mainboard code, then initialize GPIOs as requested.

BUG=chrome-os-partner:22863
TEST=Manual. Using bayleybay GPIO table, set UART GPIOs to 'function 1',
and verify UART still works after GPIO configuration. Also, verify
legacy GPIO config is functional by toggling test pin.
