[linux-sunxi] [PATCH 1/2] arm64: dts: allwinner: a64: Update Orange Pi Win/Win Plus

[Samuel Holland]

Enable the following board hardware features:
- Gigabit Ethernet
- SDIO Wi-Fi on mmc1
- SPI flash on spi0
- Status LED
- Dual-role micro-USB connection

Also provide nodes for the UARTs exposed by the 40-pin GPIO header.

A couple of fixes were made:
- Updating a couple of regulators from the schematic
- Marking the CPU's power supply as such
