The ast2600 is a new generation of SoC from ASPEED. Similarly to the
ast2400 and ast2500, it has a GPIO controller for it's 3.6V GPIO pins.
Additionally, it has a GPIO controller for 36 1.8V GPIO pins. These
voltages are fixed and cannot be configured via pinconf, so we have two
separate drivers for them.
