ARM: dts: sunxi: add MangoPi MQ-R-T113 board 

The MangoPi MQ-R-T113 is a small SBC with the Allwinner T113-s3 SoC.
The SoC features two Arm Cortex-A7 cores and 128 MB of co-packaged DDR3
DRAM. The board adds mostly connectors and the required regulators, plus
a Realtek RTL8189FTV WiFi chip.
Power comes in via a USB-C connector wired as a peripheral, and there is
a second USB-C connector usable as a host port.

Add a .dtsi file describing most of the board's peripherals, and include
that from the actual board .dts file. This allows to re-use the .dtsi
for the MQ-R-F113 RISC-V variant of that board.
