baytrail: Add functions to peek at GPIO input values

- Add functions to peek at GPIO input pad values (need to be used from
      romstage for board ram_id GPIOs)
    - Modify UART GPIOs to use existing fn-assignment function

TEST=Manual. Add debug print and verify that GPIO functions return input
    values. Also, verify UART still functions in romstage.
