This was supposed to be a performance improvement. However this is found 
to be resolving a DMIC clock discrepancy and suspect is it happens 
because of back to back quick PLLA updates. Thought it would be safer to 
have this fix in stable releases. May be I should mention these points 
to justify the 'Fixes' and 'stable' tag?
