[PATCH 1/2] ASoC: imx-card: Set mclk for codec

[Shengjiu Wang <shengjiu.wang@nxp.com>]

From: Chancel Liu <chancel.liu@nxp.com>

In some cases, ASoC machine driver may modify the mclk frequency
according to sample rate but the value in codec is still initial
frequency which should be replaced. For example, we should update
mclk before setup for cs42xx8 mclk relating registers.
