It might be nice to explicitly enumerate which variants (or rather, I
suppose which exact compatible values) support which optional clocks.
However, I suppose it's fine to just say "go read the HW manual" instead.
So, this patch,

(although this patch isn't backwards-compatible since before now, DT
nodes didn't need to provide any entries in clocks)
