ARM: sun8i: Add Parrot Board DTS
The Parrot Board is an evaluation board with an Allwinner R16 (assumed to be close to an Allwinner A33), 4GB of eMMC, 512MB of RAM, USB host and OTG, a WiFi/Bluetooth combo chip, a micro SD Card reader, 2 controllable buttons, an LVDS port with separated backlight and capacitive touch panel ports, an audio/microphone jack, a camera CSI port, 2 sets of 22 GPIOs and an accelerometer.
