ASoC: simple-card-utils: Do not handle device clock

This reverts commit 1e30f642cf ("ASoC: simple-card-utils: Fix device
module clock"). The original patch ended up breaking following platform,
which depends on set_sysclk() to configure internal PLL on wm8904 codec
and expects simple-card-utils to not update the MCLK rate.
 - "arch/arm64/boot/dts/freescale/fsl-ls1028a-kontron-sl28-var3-ads2.dts"

It would be best if codec takes care of setting MCLK clock via DAI
set_sysclk() callback.
