ARM: Kirkwood: support 98DX412x kirkwoods with pinctrl 



The Marvell 98DX412x SoC embed a kirkwood variant that does not have
pinctrl support yet. Even though this kirkwood is very similar to the
88f6281, on the MPP front a lot of pins are not available. That's why a
new kirkwood pinctrl variant is needed.

This driver supports all kirkwood variants, i.e. 88f6180, 88f619x, and 88f628x.

It also support the 88f6281-based variant in the 98dx412x Bobcat SoCs.
