ARM: dts: sun9i: Add a dts for the armadillo board

Armadillo is a A80 based Qseven module with up to 4GB DDR3, eMMC,
SPI NR Flash, HDMI, LVDS, eDP, DSI, CSI, 5 USB Host ports, 1 USB 3.0
OTG port, USB to SATA bridge, Gigabit Ethernet and an Offload STM32
Cortex-M0 processor providng CAN, RTC and fan controller functionality.
