Subject: [PATCH 4.0 46/72] ASoC: rt5677: fixed wrong DMIC ref clock

4.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bard Liao <bardliao@...ltek.com>

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.
