With this, five platforms are moving to the relatively new pinctrl
subsystem for their pin management, replacing the older soc specific
in-kernel interfaces with common code.
There is quite a bit of net addition of code for each platform being
added to the pinctrl subsystem. but the payback comes later when adding
new boards can be done by only providing new device trees instead.

This adds pinctrl driver for SPEAr13xx family. SPEAr13xx family supports two
machines: SPEAr1310 and SPEAr1340.

The spear/pinctrl branch has hard dependencies on both the
pinctrl branch and the clkdev branch. We merge those here
to fix it up without having to rebase a branch that has
been pulled into other stable branches already.

Add pinctrl support for Freescale MXS SoCs, i.MX23 and i.MX28.

The driver has mux and config support while the gpio is still
not supported.
For select input setting, the driver will handle it internally
and do not need user to take care of it.
The pinctrl-imx core driver will parse the dts file and dynamically
create the pinmux functions and groups.
Each IMX SoC pinctrl driver should register pins with a pin register map
including mux register and config register and select input map to core
for proper operations.

Define a new binding for the Tegra pin controller, which is capable of
defining all aspects of desired pin multiplexing and pin configuration.
This is all based on the new common pinctrl bindings.
Add Tegra30 binding based on Tegra20 binding.
Add some basic stuff that was missing before:
* How many and what reg property entries must be provided.
* An example.

This places the file in the new location for all pin controller bindings.
Also, rename the file using the full compatible value for easier
avoidance of conflicts between multiple bindings.

The core pin controller bindings define:
* The fact that pin controllers expose pin configurations as nodes in
device tree.
* That the bindings for those pin configuration nodes is defined by the
individual pin controller drivers.
* A standardized set of properties for client devices to define numbered
or named pin configuration states, each referring to some number of the
afore-mentioned pin configuration nodes.
* That the bindings for the client devices determines the set of numbered
or named states that must exist.
