Subject: ASoC: rt5677: fixed wrong DMIC ref clock

From: Bard Liao <[email protected]>

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.
