ARM: dts: sun8i: Add dts for Orange Pi 2 SBC

The Orange Pi 2 is a SBC based on the Allwinner H3 SoC with a uSD slot,
4 USB ports connected via a USB-2 hub, a 10/100M ethernet port using the
SoC's integrated PHY, Wifi via a RTL8189ETV sdio wifi chip, USB OTG, HDMI,
a TRRS headphone jack for stereo out and composite out, a microphone,
an IR receiver, a CSI connector, 2 LEDs, a 3 pin UART header
and a 40-pin GPIO header.
