The clock is done primarily for the newer Omega SoC. I hope, we will
upstream the devicetree file for Omega soon.

The existing NS2 and Stingray SoC's, default to proper values in the
hardware registers, so they did not need to specify the clock. They
will also work over sleep cycles for the same reason.

But, I will ask around to see if we can add the clock for those
SoC's as well.

Thanks
Arun
