ARM: dts: sun8i: s3l: add support for Pine64 PineCube IP camera

The Pine64 PineCube IP camera is an IP camera with SoChip S3 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 and a Realtek
RTL8189ES SDIO Wi-Fi module. A RGB LCD connector is reserved on the
board.

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

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