Commit 8c8a777 (ARM: OMAP2+: Add function to read GPMC settings from device-tree) added a device-tree property "gpmc,device-nand" to indicate is the GPMC child device is NAND. This commit should have updated the GPMC NAND documentation (Documentation/devicetree/bindings/mtd/gpmc-nand.txt) to list the property "gpmc,device-nand" as a required property and also updated the example. However, this property is redundant and not needed because the GPMC child device node for NAND is called "nand". Therefore, remove this property.
