Hmmm, I don't really like that bit too much.

This "pll5" clock doesn't actually exist at the hardware point of
view, which is not really what the DT is used for.

I can think of two ways to do what you want withouth this: 
  - either hardcode the name, since we have a compatible of our own here
  - or use strchr to take anyhing until '_' and use that as a name
