PATCH v2 1/1 pinctrl: mscc: Add gpio and pinctrl driver for MSCC MIPS SoCs (VcoreIII based)

This driver supports the pin and gpio controller found in the Ocelot and Luton SoCs.

The driver was inspired from the pinctrl driver in Linux, but was simplified and was modified to allow supporting an other SoCs (Luton).

For Ocelot and Luton the controller is the same, only the pins to program differ.
