riscv: dts: allwinner: Add MangoPi MQ devicetree 



The MangoPi MQ is a tiny SBC built around the Allwinner D1s. Its
onboard peripherals include two USB Type-C ports (1 device, 1 host)
and RTL8189FTV WLAN.

A MangoPi MQ-R variant of the board also exists. The MQ-R has a
different form factor, but the onboard peripherals are the same.

Most D1 and D1s boards use a similar power tree, with the 1.8V rail
powered by the SoC's internal LDOA, analog domains powered by ALDO,
and the rest of the board powered by always-on fixed regulators. To
avoid duplication, factor out the regulator information that is
common across boards.

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