riscv: dts: allwinner: Add Allwinner D1 Nezha devicetree 



"D1 Nezha" is Allwinner's first-party development board for the D1 SoC.
It was shipped with 512M, 1G, or 2G of DDR3. It supports onboard audio,
HDMI, gigabit Ethernet, WiFi and Bluetooth, USB 2.0 host and OTG ports,
plus low-speed I/O from the SoC and a GPIO expander chip.
