sorry, i should explain more in the commit msg...

just to clarify, this property is replaced by 
"realtek,dmic-init-delay-ms" in rt5514 driver:

a5461fd6c8f7 ASoC: rt5514: Add the DMIC initial delay to wait it ready.

which does exactly the same thing as the old one: perform a delay after 
set clk...

i can do that if you still insist to keep it, since it's harmless :)
