[PATCH] ASoC: imx-audmix: release cpu_mclk clock at failure

[Shengjiu Wang]

When defer probe happens, there may be below error:

platform 59820000.sai: Resources present before probing

The cpu_mclk clock is from the cpu dai device, if it is
not released, then the cpu dai device probe will fail
for the second time.
