ARM: dts: sun6i: Add new dts file for tablets using the inet-q972 PCB

Add a dts file for tablets using the generic inet-q972 PCB.

Tablets with this PCB feature a mini-hdmi output, micro-usb usb-host,
micro-usb usb-otg, 3.5mm headphone jack, a micro sd slot,
(mini) power-barrel and an usb wifi module.

This has been tested on a 9.7" 1024x768 qware qw tb9718-qhd tablet.
