In case this isn't enough then the loop should be run for any one CPU
from each cluster.
That will guarantee that we have completed regulator/clk
initialization for all the clusters..
But checking for all CPUs might be fine as well..

The deal is that we aren't yet sure if we are really required to check
this for all CPUs.
So, we are waiting for the first platform to break and can be fixed
then. So, just leave it
as is for now :)

Thanks for caring for it :)
