The changes contained on this patch should be part of another patch. I
can't really review this if I don't know how those things, especially
enum skl_dpll are going to be used. And it also makes the lives of
backporters harder.
Also, I guess that a patch with 3 signed-off-by stamps shouldn't
really need an additional reviewed-by stamp, right? So maybe this
should just be merged.
