Looks to me like these are all the same h/w, but just have differing sets of clocks. That's not really a reason to have different compatibles. If you need to know what clocks are present, you can walk the DT for all 'clocks' properties matching this clock controller instance. Or use 'clock-indices' to define which ones are present.
