[PATCH 00/11] pinctrl: mvebu: remove hardcoded addresses from Dove pinctrl

This patch set is one required step for Dove to hop into mach-mvebu.
Until now, pinctrl-dove was hardcoding some registers that do not
directly belong to MPP core registers. This is not compatible with
what we want for mach-mvebu.

This patch set removes all hardcoded addresses from pinctrl-dove
by either requesting additional resources or requesting a syscon
provided regmap for global config registers. As this changes existing
driver to DT binding relationship, all additional resources are
probed in a backward compatible way. If the corresponding resource
cannot be found, we derive it from the existing pinctrl resource
and warn about the old DTB firmware.

Patch 1 and 2 add or update binding documentation for dove, global
config syscon, and pinctrl-dove. The latter also documents missing reg
property requirement for other mvebu pinctrl nodes.

Patch 3 and 4 add the new pinctrl reg property values and global config
register syscon to exisiting dove.dtsi.

Patch 5 fixes a misdesign of common mvebu pinctrl driver, that
requested the resource instead of getting it from the SoC specific
driver stub.

Patches 6 and 7 now add requests to the new resources in a backward
compatible way, while patches 8-11 make use of those resources.

At the end, there is no more hardcoded addresses in pinctrl-dove.

The patch set is based on pre-v3.14-rc1 mainline. I suggest to take
this in as v3.15 stuff. Since more Dove/mach-mvebu related patches
will likely follow, Jason should prepare a topic branch for LinusW
to pull from?

It has been boot tested on Dove and compile tested only for Kirkwood,
Armada 370 and XP.
