[PATCH V2] ASoC: imx-audmux: remove unnecessary check of clk_disable_unprepare/clk_prepare_enable

[cgel.zte at gmail.com]

From: Minghao Chi <chi.minghao at zte.com.cn>

Because clk_disable_unprepare/clk_prepare_enable already checked NULL clock
parameter, so the additional checks are unnecessary, just remove them.
