[U-Boot] [PATCH v6 05/27] mtd: add get/set of_node/flash_node helpers

From: Brian Norris <computersforpeace@gmail.com>

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.
