I don't see how this is useful. Is the new driver so generic it
doesn't know what clocks it's outputting? We've been trying to
move people away from using clock-output-names, so most likely
this sort of information should be conveyed from DT via the
compatible string and a table in the driver that matches up the
compatible string with the list of clock names.

Noise. Please remove.
