mtd: add get/set of_node/flash_node helpers
Linux commit 28b8b26b308 ("mtd: add get/set of_node/flash_node helpers") We are going to begin using the mtd->dev.of_node field for MTD device nodes, so let's add helpers for it. Also, we'll be making some conversions on spi_nor (and nand_chip eventually) too, so get that ready with their own helpers.
