pinctrl: mvebu: add pin-muxing driver for the Marvell Armada 380/385

The Marvell Armada 380/385 are new ARM SoCs from Marvell, part of the
mvebu family, but using a Cortex-A9 CPU core. In terms of pin-muxing,
it is similar to Armada 370 and XP for the register layout, only
different in the number of available pins and their
functions. Therefore, we simply use the existing
drivers/pinctrl/mvebu/ infrastructure, with no other changes that the
list of pins and corresponding functions.

+* Marvell Armada 380/385 SoC pinctrl driver for mpp
+
+Please refer to marvell,mvebu-pinctrl.txt in this directory for common binding
+part and usage.
+
+Required properties:
+- compatible: "marvell,88f6810-pinctrl", "marvell,88f6820-pinctrl" or
+  "marvell,88f6828-pinctrl" depending on the specific variant of the
+  SoC being used.
+- reg: register specifier of MPP registers
+
+Available mpp pins/groups and functions:
+Note: brackets (x) are not part of the mpp name for marvell,function and given
+only for more detailed description in this document.
