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.
