ARM: dts: meson8b: odroidc1: use the MAC address stored in the eFuse
Odroid-C1 uses the MAC address stored in eFuse at offset 0x1b4 (which is defined as a "standard" offset for all Meson8 and Meson8b boards, but testing shows that MXQ doesn't have the eFuse values programmed and EC-100 stores it's MAC address in eMMC). Add the nvmem cell which points to the MAC address and asssign it to the Ethernet controller as "mac-address". As result of this the MAC address which is stored in the eFuse is now assigned to the Ethernet controller and consistent across reboots.
