[PATCH v4 08/12] riscv: dts: allwinner: Add MangoPi MQ Pro devicetree

[Samuel Holland]

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.

(no changes since v3)

Changes in v3:
 - Drop mmc alias
 - Change LED_FUNCTION_BACKLIGHT to LED_FUNCTION_STATUS (the backlight
   regulator is disconnected by default, so this is a standalone LED)

Changes in v2:
 - Added LED (GPIO shared between onboard LED and backlight regulator)
