The purpose of the created zynq-7000.dtsi file is to describe the
hardware common to all Zynq 7000-based boards.  Also, get rid of the
zynq-ep107 device tree, since it is not hardware anyone can purchase.

Add a zc702 dts file based on the zynq-7000.dtsi.  Add it to the
dts/Makefile so it is built with the 'dtbs' target.

Not going to apply this. We need to finish our discussion in
"[PATCH v4 1/5] zynq: use GIC device tree bindings" before.

Definitely I like idea to use "xlnx,zynq-7000" generic model name.

Thanks,
Michal
