[PATCH v3] ARM: sun5i: Add DT for HSG H702 tablet board

[PATCH v3] ARM: sun5i: Add DT for HSG H702 tablet board

[Chen-Yu Tsai]

This is a Q8 format 7 inch tablet with an Allwinner A13 SoC.
It has 512MB DRAM, 4GB NAND flash, an accelerometer, camera,
RTL8188-based WiFi, and micro SD slot for external storage.

It is likely made by a subsidiary of Hanns.G (Hannstar).

Note that checkpatch.pl is not happy about having the FSF address in
the file. Given that the dts files are intended to be redistributable
independent of the kernel, I think this error can be ignored.

Changes since v2:

 - Dual license under GPL/X11.
 - Use extra fixed regulator for usb1-vbus.

Sorry if I have not been clear enough, but what I meant was that we
could probably create a 5v regulator in sunxi-common-regulators. It
will probably be useful for other boards in the same case, so we'd
better put it there, instead of redefining it everywhere (just like we
did for reg_vcc3v and reg_vcc3v3)
