ARM: dts: sunxi: add support for RerVision A33-Vstar board 



RerVision A33-Vstar board is a board based on their A33-Core1 SoM (A33
SoC + 512MiB DRAM + 4GiB eMMC + AXP223 PMIC), with multiple peripherals:

- MicroSD card slot
- 4.0mm/1.7mm DC jack connected to ACIN of AXP223 (and a XH2.54 2-pin
  connector for alternative 5V DC IN)
- OTG-capable microUSB port
- Reserved pads for soldering Li-ion battery and/or 3V RTC battery
- 3 LRADC-attached keys and 2 fixed function power/reset keys
- AP6212 Wi-Fi/BT combo module
- On-board GL850G hub attached to the USB host port of A33, and a
  RTL8152 USB Ethernet chip at the downstream of the hub
- Onboard microphone (not supported yet) and headphone jack
- 3 UART ports as PH2.0 3-pin connectors (UART2 one is currently used as
  debug output and others are ignored yet)
