Add support for the National Instruments 169445 board
----
Changes from v3:
- Remove unused ngpios DT property from documentation for the NAND GPIO
bindings and the actual board device tree.
- Add no-output property to the same, for the GPIO controller that is only
used for input signals from NAND.
The GPIO-based NAND controller on National Instruments 169445 hardware
exposes a set of simple lines for the control signals.

+Bindings for the National Instruments 169445 GPIO NAND controller
+
+The 169445 GPIO NAND controller has two memory mapped GPIO registers, one
+for input (the ready signal) and one for output (control signals). It is
+intended to be used with the GPIO NAND driver.
+
+Required properties:
+ - compatible: should be "ni,169445-nand-gpio"
+ - reg-names: must contain
+ "dat" - data register
+ - reg: address + size pairs describing the GPIO register sets;
+ order must correspond with the order of entries in reg-names
+ - #gpio-cells: must be set to 2. The first cell is the pin number and
+ the second cell is used to specify the gpio polarity:
+ 0 = active high
+ 1 = active low
+ - gpio-controller: Marks the device node as a gpio controller.
+
+Optional properties:
+ - no-output: disables driving output on the pins
+
+Examples:
+ gpio1: nand-gpio-out@1f300010 {
+ compatible = "ni,169445-nand-gpio";
+ reg = <0x1f300010 0x4>;
+ reg-names = "dat";
+ gpio-controller;
+ #gpio-cells = <2>;
+ };
+
+ gpio2: nand-gpio-in@1f300014 {
+ compatible = "ni,169445-nand-gpio";
+ reg = <0x1f300014 0x4>;
+ reg-names = "dat";
+ gpio-controller;
+ #gpio-cells = <2>;
+ no-output;
+ };

IMO, this shouldn't be in the kernel. Is the kernel supposed to
create board specific images for every bootloaders custom format? It
doesn't scale.

This is how the linux MIPS tree is doing generic kernels. Ralf, care to
