[PATCH 14/14] ARM: dts: sun8i: s3l: add support for Pine64 Single Cube Computer

[Icenowy Zheng]

The Single Cube Computer kit by Pine64 is a development kit with
Allwinner S3L SoC.

It comes with a main board, an expansion board and a camera.

The main board features a Micro-USB power-only jack, a USB Type-A port,
an Ethernet port connected to the internal PHY of the SoC. A RGB LED
port is reserved on the board.

The expansion board features a TF slot, a microphone and a speaker
connector with on-board amplifier.

Add support for the kit, with features on the main board and the
expansion board now.
