Can you eliminate these extra '\n' in these assigments while you're
here? I think they should all fit within the 80 col rule now.
Also another ocd you could do is order the assignments in a better
looking way. I'd suggest either get,set,calc or calc,set,get.

bxt before skl if we want to be chronologically pedantic?

hsw will look a bit lonely in the middle here, but I suppose that's
not sufficient reason to upstream my hsw_set_cdclk :P

chv before bdw?
