4.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bard Liao <bardliao@xxxxxxxxxxx>
commit 60a8d62b8497c23eb3d48149af7e55dac2dd83a2 upstream.
DMIC clock source is not from codec system clock directly. it is
generated from the division of system clock. And it should be 256 *
sample rate of AIF1.
