[PATCH v2] sunxi: add PineCube board

[Icenowy Zheng]

PineCube is an IP camera development kit released by Pine64.

It comes with the following compoents:

- A mainboard with Sochip S3 SoC, a 16MByte SPI Flash, AXP209 PMIC,
a power-only microUSB connector, a USB Type-A connector, a 10/100Mbps
Ethernet port and FPC connectors for camera and daughter board.
- An OV5640-based camera module which is connected to the parallel CSI
bus of the mainboard.
- A daughterboard with several buttons, a SD slot, some IR LEDs, a
microphone and a speaker connector.

As the device tree is synchronized in a previous commit, just add
MAINTAINER item and a defconfig.
