Do we need to have this disabled initially in the SoC dtsi?

Also, common style in this file is to add a blank line between nodes.
Please keep it.

It's in SoC, and don't affect anything outside of Soc. So I think
it can be enabled by default.

It seems that the patch is meant to have dts changes only by reading
the subject.  So it might be good to get clk-imx6q.c out of here.
