The Orange Pi PC 2 is a typical single board computer using the Allwinner H5 SoC. Apart from the usual suspects it features three separately driven USB ports and a Gigabit Ethernet port. Also it has a SPI NOR flash soldered, from which the board can boot from. This enables the SBC to behave like a "real computer" with built-in firmware.
Add the board specific .dts file, which includes the H5 .dtsi and enables the peripherals that we support so far.
