ASoC: arizona: Add delay for output disable

Browse Source 
Give the output disable sequence a chance to fully complete, otherwise
there is a danger we may remove the clock before it is finished
resulting in a pop noise. The delay for each output must be cumulative
and these are coalesced into a single delay.
