superio/ite/common: Add common driver for GPIO and LED configuration
Add a generic driver to configure GPIOs and LEDs on common ITE
SuperIOs. The driver supports most ITE SuperIOs, except Embedded
Controllers. The driver allows configuring every GPIO property
with pin granularity.
Verified against datasheets of all ITE SIOs currently supported by
coreboot, except IT8721F (assumed to be the same as IT8720F),
IT8623E and IT8629E.
