Subject: [PATCH 031/117] riscv: dts: allwinner: Add MangoPi MQ Pro devicetree

The MangoPi MQ Pro is a tiny SBC with a layout compatible to the
Raspberry Pi Zero. It includes the Allwinner D1 SoC, 512M or 1G of DDR3,
and an RTL8723DS-based WiFi/Bluetooth module.

The board also exposes GPIO Port E via a connector on the end of the
board, which can support either a camera or an RMII Ethernet PHY. The
additional regulators supply that connector.
