A table for P? Why?

I was discussing exactly this the other day with Mike. He has a bunch
of patches to address exactly that issue. He plans on posting it and
merge it by 4.8. Until then, we should rely on the hardcoded clock
string like it's done there, and we should obviously add the clocks in
the DT node for when we will actually use them.

Yeah, I know, but I feel like it's a feature here, since Linux should
never modify that clock anyway.

I can add a comment though.

I liked the similar layout across all the clocks, comparing to other
clocks that have a longer name or parent name.

None, and it seems like it's not used by any downstream device either.
