Based on the IRC discussion we had, I would think that the "prcc" clocks would best be represented using multiple clock-cells since you can describe them easily a tuple of register index, bit number some way to distinguish the two types.
The "prcmu" clocks are harder, and we probably need either a more verbose representation using one node per clock there, or have a single node for the entire prcmu and not bother to describe them in DT but hardcode everything in the source. The current patch does the latter, which is easier now but means we cannot simplify the code much in the future when we remove ATAGS boot support.
I hope Mike can give some better insight to what his preferences are.
