[PATCH 0/2] arm64: dts: meson-gxbb-odroidc2: eFuse MAC address and LED properties

Two small device-tree updates for the Hardkernel ODROID-C2, found while
adding OpenWrt support for the board.

Patch 1 wires the eth_mac eFuse nvmem cell (already described in
meson-gx.dtsi, but so far unused) to the Ethernet controller, so the
kernel reads the factory MAC address itself instead of relying on the
bootloader or a random fallback.

Patch 2 converts the blue status LED to the standard color/function
properties.

Both verified on ODROID-C2 hardware and rechecked against this tree
with CHECK_DTBS=y W=1.
