[PATCH 1/3] ASoC: adau1372: fix mclk

[Maarten Zanders]

"mclk" is retrieved from the configuration and assigned to adau1372->clk.
However adau1372->mclk (==NULL) is used for clk_prepare_enable() and
clk_disable_unprepare() which don't have any effect.

Remove .clk from struct adau1372 and use .mclk throughout.
This change ensures that the input clock is switched on/off when the
bias level is changed.
