Configure the pinctrl as it required to make some IO controllers working (USB/UART/I2C/...). The idea would be in the next version to modify the pch GPIO driver and configure these pins through the device tree.
These modifications are ported from the coreboot project.

Why undef these two? The BayTrail SoC does support GPIO banks in the legacy bridge.
