pinctrl: mvebu: add pinctrl driver for Armada XP 

This adds a pinctrl driver for pin muxing on Marvell Armada XP. The
driver is ported from Linux and modified to fit on Barebox's common
mvebu pinctrl driver.

* This file supports the three variants of Armada XP SoCs that are
* available: mv78230, mv78260 and mv78460. From a pin muxing
* perspective, the mv78230 has 49 MPP pins. The mv78260 and mv78460
* both have 67 MPP pins (more GPIOs and address lines for the memory
* bus mainly). The only difference between the mv78260 and the
* mv78460 in terms of pin muxing is the addition of two functions on
* pins 43 and 56 to access the VDD of the CPU2 and 3 (mv78260 has two
* cores, mv78460 has four cores).
