gpncore config tables were previously missing -- add them.
Also, make the baytrail GPIO/PAD LUTs easier to read.
TEST=Manual. Build + boot on bayleybay.

- 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.

During ramstage, call mainboard_get_gpios to get initial GPIO configuration
from the mainboard code, then initialize GPIOs as requested.

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.
