ARM: dts: sun5i: Add dts file for the Empire Electronix M712 tablet

Add a dts file for the Empire Electronix M712 tablet, this is a 7" A13
tablet, with micro-usb (otg), headphone and micro-sd slots on the
outside. It uses a Goodix gt811 touchscreen controller, a RTL8188CTV
wifi chip and a DMART06 (1238a4) accelerometer.

Note currently the dts for this is somewhat empty. This will change
once we add support for the touchscreen and accelerometer.
