pinctrl: sunxi: Add A80 special pin controller 

Like the previous designs, the A80 has a special pin controller for the
critical pins, like the PMIC bus.

Add a driver for this controller.

[wens: Add A80 compatible strings to bindings doc; fix pin function
       names based on v1.3 datasheet; constify of_device_id table]
