Please explain why. What's going on, why we need the revert.

It's fine to reply here, the commit message can be amended by whoever
applies the patch.

BR,
Jani.

Yes, 

Unfortunately according to our recent findings there is still some
unidentified factor, requiring CDCLK to be set higher - otherwise we 
still get underruns on some multipipe configurations, despite CDCLK being set
according to BSpec formula. So getting again back into debug mode to
indentify the cause, meanwhile setting CDCLK=Pixel rate back in order
to remove regression in 10% of the cases due to FIFO underruns.
