Looks like yet another clock ordering setup. I guess different Amlogic
platforms have slightly different ordering requirements.

Neil, do you have any idea of which platform requires which ordering?
The variability in DT and platforms is pretty difficult to follow (and
I don't think I have such board around).

Thanks,
