Add pinctrl support for Freescale MXS SoCs, i.MX23 and i.MX28.
The driver supports device tree probe only.

+* Freescale MXS Pin Controller
+
+The pins controlled by mxs pin controller are organized in banks, each bank
+has 32 pins. Each pin has 4 multiplexing functions, and generally, the 4th
+function is GPIO. The configuration on the pins includes drive strength,
+voltage and pull-up.
+
+Required properties:
+- compatible: "fsl,imx23-pinctrl" or "fsl,imx28-pinctrl"
+- reg: Should contain the register physical address and length for the
+ pin controller.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+The pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for
+a group of pins, and only affects those parameters that are explicitly listed.
+In other words, a subnode that describes a drive strength parameter implies no
+information pull-up. For this reason, even seemingly boolean values are
+actually tristates in this binding: unspecified, off, or on. Unspecified is
+represented as an absent property, and off/on are represented as integer
+values 0 and 1.
+
+Those subnodes will fall into two categories. One is to set up a group of
+pins for a function, both mux selection and pin configurations. For the same
+function, all pin group nodes should use the same node name and be sorted
+together in "reg" value. And the other one is the pure pin configuration
+node, which are used to configure some pins that need a different drive
+strength, voltage or pull-up configurations from what specified in the pin
+group node.
+
+Required subnode-properties:
+- fsl,pinmux-ids: An integer array. Each integer in the array specify a pin
+ with given mux function, with bank, pin and mux packed as below.
+
+ [15..12] : bank number
+ [11..4] : pin number
+ [3..0] : mux selection
+
+ For the pure pin configuration nodes, the mux selection packed in the
+ integer takes no effect, which means the mux selection of the pins that
+ need separate configuration will also have to be set up by group node.
+ In other word, the pin group node should include all the pins for given
+ function, regardless of whether separate pin configuration nodes are needed
+ to configure some pins differently or not.
+
+ Valid values for these integers are listed below.
+
+- reg: Should be the index of the pin group nodes for same function. This
+ property is required only for pin group nodes, and should not be present
+ in any pure pin configuration nodes.
+
+Optional subnode-properties:
+- fsl,drive-strength: Integer.
+ 0: 4 mA
+ 1: 8 mA
+ 2: 12 mA
+ 3: 16 mA
+- fsl,voltage: Integer.
+ 0: 1.8 V
+ 1: 3.3 V
+- fsl,pull-up: Integer.
+ 0: Disable the internal pull-up
+ 1: Enable the internal pull-up
+
+Examples:
+
+pinctrl at 80018000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "fsl,imx28-pinctrl";
+ reg = <0x80018000 2000>;
+
+ mmc0_4bit_pins_a: mmc0-4bit at 0 {
+ reg = <0>;
+ fsl,pinmux-ids = <
+ 0x2000 0x2010 0x2020 0x2030
+ 0x2080 0x2090 0x20a0>;
+ fsl,drive-strength = <1>;
+ fsl,voltage = <1>;
+ fsl,pull-up = <1>;
+ };
+
+ mmc0_4bit_pins_b: mmc0-4bit at 1 {
+ reg = <1>;
+ fsl,pinmux-ids = <
+ 0x2040 0x2050 0x2060 0x2070
+ 0x2080 0x2090 0x20a0>;
+ fsl,drive-strength = <1>;
+ fsl,voltage = <1>;
+ fsl,pull-up = <1>;
+ };
+
+ mmc0_cd_cfg: mmc0-cd-cfg {
+ fsl,pinmux-ids = <0x2090>;
+ fsl,drive-strength = <1>;
+ fsl,voltage = <1>;
+ fsl,pull-up = <0>;
+ };
+
+ mmc0_sck_cfg: mmc0-sck-cfg {
+ fsl,pinmux-ids = <0x20a0>;
+ fsl,drive-strength = <2>;
+ fsl,voltage = <1>;
+ fsl,pull-up = <0>;
+ };
+};
+
+In this example, there are two pin groups mmc0_4bit_pins_a and mmc0_4bit_pins_b
+for function mmc0-4bit. These two groups of pins have the first 4 pins (data)
+be different, and the last 3 pins (card-detect, command, clock) be same. The
+card-detect and clock pins require different pin configuration than the group.
+
+Valid values for i.MX28 pinmux-id:
