OF: MTD: make plat_nand loadable from DT
This patch sets the of_match_table field inside plat_nand's platform_driver. We also add a struct mtd_part_parser_data pointer to make sure of_part parsing works. If an arch wants to support plat_nand via DT it needs to setup the platform_nand_data and hook it into the platform_device.
