MIPS: dts: jz4780/ci20: Add NEMC, BCH and NAND device tree nodes

78800558d104e003f9ae92e0107f1de39cf9de9f

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.

Harvey's latest version.]
