NXP LPC32xx SoC NAND SLC controller

Required properties:
- compatible: "nxp,lpc3220-slc"
- reg: Address and size of the controller
- nand-on-flash-bbt: Use bad block table on flash
- gpios: GPIO specification for NAND write protect

The following required properties are very controller specific. See the LPC32xx
User Manual:
- nxp,wdr-clks: Delay before Ready signal is tested on write (W_RDY)
- nxp,rdr-clks: Delay before Ready signal is tested on read (R_RDY)
(The following values are specified in Hz, to make them independent of actual
clock speed:)
- nxp,wwidth: Write pulse width (W_WIDTH)
- nxp,whold: Write hold time (W_HOLD)
- nxp,wsetup: Write setup time (W_SETUP)
- nxp,rwidth: Read pulse width (R_WIDTH)
- nxp,rhold: Read hold time (R_HOLD)
- nxp,rsetup: Read setup time (R_SETUP)

Optional subnodes:
- Partitions, see Documentation/devicetree/bindings/mtd/partition.txt

Example:

	slc: flash@20020000 {
		compatible = "nxp,lpc3220-slc";
		reg = <0x20020000 0x1000>;
		#address-cells = <1>;
		#size-cells = <1>;

		nxp,wdr-clks = <14>;
		nxp,wwidth = <40000000>;
		nxp,whold = <100000000>;
		nxp,wsetup = <100000000>;
		nxp,rdr-clks = <14>;
		nxp,rwidth = <40000000>;
		nxp,rhold = <66666666>;
		nxp,rsetup = <100000000>;
		nand-on-flash-bbt;
		gpios = <&gpio 5 19 1>; /* GPO_P3 19, active low */

		mtd0@00000000 {
			label = "phy3250-boot";
			reg = <0x00000000 0x00064000>;
			read-only;
		};
