Subject: [PATCH] ARM: dts: sun8i: s3: pinecube: add ethernet alias for Wi-Fi

The PineCube board has a RTL8189ES Wi-Fi module on board, and the module
doesn't have any MAC address programmed in.

Add a ethernet alias in the DT, thus the bootloader will then be able to
generate a MAC address into the device tree node of Wi-Fi.
