As we know that old clock binding will not be used and maintained anymore and all device node
will be moved Into each SS dtsi, so I'm not sure if we should still introduce such a big change using
the known deprecated things now. May be better to hold on a bit and wait for Shawn's suggestion
on the pending dts re-org patchset first.
