mtd: plat_nand: add platform probe/remove callbacks
Add optional probe and remove callbacks to the plat_nand driver. Some platforms may require additional setup, such as configuring the memory controller, before the nand device can be accessed. This patch provides an optional callback to handle this setup as well as a callback to teardown the setup.
