Add device tree nodes for the NEMC and BCH to the JZ4780 device tree, and make use of them in the Ci20 device tree to add a node for the board's NAND. Note that since the pinctrl driver is not yet upstream, this includes neither pin configuration nor busy/write-protect GPIO pins for the NAND. Use of the NAND relies on the boot loader to have left the pins configured in a usable state, which should be the case when booted from the NAND.
