This adds some defines and helper functions for the common mpp reg
layout to mvebu pinctrl include.

The only valuable information a special callback can derive from
mvebu_mpp_ctrl passed to it, is the pin id. Instead of passing
the struct, pass the pid directly.

Like the spear platform, the mvebu platform has multiple files: one
core file, and then one file per SoC family. More files will be added
later, as support for mach-orion5x and mach-mv78xx0 SoCs is added to
pinctrl-mvebu. For those reasons, having a separate subdirectory,
drivers/pinctrl/mvebu/ makes sense, and it had already been suggested
by Linus Wallej when the driver was originally submitted.

This patch adds a pinctrl driver core for Marvell SoCs plus DT
binding documentation. This core driver will be used by SoC family
specific drivers, i.e. Armada XP, Armada 370, Dove, Kirkwood, aso.
