[RFC v3 7/9] MIPS: DTS: CI20: make DM9000 Ethernet controller use NVMEM to find the default MAC address

There is a default MAC address factory programmed into
the eFuses of the JZ4780 chip. By using this every CI20
board has an individual but stable MAC address and DHCP
can assing stable IP addresses.
