MTD: pxa3xx-nand: add devicetree bindings
This patch contains a hack to get the DMA resources of the device when probed from a devicetree node. This can be removed once a generic DMA controller framework lands. A mtd_part_parser_data is passed mtd_device_parse_register which contains a reference to the device node, so MTD partitions can be added as children.

+PXA3xx NAND DT bindings
+
+Required properties:
+
+ - compatible: Should be "marvell,pxa3xx-nand"
+ - reg: The register base for the controller
+ - interrupts: The interrupt to map
+ - #address-cells: Set to <1> if the node includes partitions
+
+Optional properties:
+
+ - marvell,nand-enable-arbiter: Set to enable the bus arbiter
+ - marvell,nand-keep-config: Set to keep the NAND controller config as set
+ by the bootloader
+ - num-cs: Number of chipselect lines to usw
+
+Example:
+
+ nand0: nand@43100000 {
+ compatible = "marvell,pxa3xx-nand";
+ reg = <0x43100000 90>;
+ interrupts = <45>;
+ #address-cells = <1>;
+
+ marvell,nand-enable-arbiter;
+ marvell,nand-keep-config;
+ num-cs = <1>;
+
+ /* partitions (optional) */
+ };
