[PATCH] ASoC: wm8524: remove constraint for FE-BE

[Fabio Estevam]

From: Shengjiu Wang <shengjiu.wang at nxp.com>

The constraint is not needed for back end bistream since
the sample rate is fixed by dts and the constraint
is propagated to front end bistream as they share the same
snd_soc_pcm_runtime.
