It wouldn't happen on each CPU, but one CPU per policy as others
would return -ENODEV.
I added dev_dbg earlier but then I thought dev_info is better as we may
better show this to everybody as it about the most important device,
i.e. CPU :)

Probably we will call of_init_opp_table() directly for other devices, as this
function doesn't do anything else, apart from some prints.. So, probably
leave is as is for now, unless a real need arises ?
