I know this isn't a new problem, but this needs a binding -- and a
different compatible from p4080-era CCF.  AFAICT it's a completely
different programming model, and even the block version registers weren't
present in the original version.

Why is clock-frequency hardcoded here rather than supplied by U-Boot? 
Especially since this is an SoC file, not a board file.

clock-output-names and fixed-clock doesn't belong on this node.

clocks should point to sysclk.
