The Linux kernel driver cannot handle Baytrail legacy GPIOs, so make the
default input GPIO type MMIO.

TEST=Manual on Rambi. Run "echo 169 > /sys/class/gpio/export; cat
/sys/class/gpio/gpio169/value", verify GPIO value changes based upon mic
jack status.

Add support for DirectIRQ / dedicated IRQs. This consists of up to 16
IRQs for both SCORE and SSUS banks.
BUG=chrome-os-partner:22863
TEST=Manual on Rambi. Set some pins to GPIO_DIRQ, and then verify DIRQ
regwrites w/ GPIO_DEBUG look correct.

In order for gpio pins to trigger an smi/sci the GPIO_ROUT
register needs to be set accordingly. For SMI, the ALT_GPIO_SMI
register needs to be enabled for each gpio as well.
The first 8 gpios from the suspend and core well are the only gpios
that can trigger an SMI or SCI. The settings for the GPIO_ROUT
and ALT_GPIO_SMI register are not commited until the SMM settings
are enabled in the southcluster.

TEST=Built and booted. Manually triggered SCI by changing GPE0a_EN
and toggling PCH_WAKE_L on the EC console.

- 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.
