[PATCH] ASoC: imx-audmux: use sysfs_emit() to instead of scnprintf()

[ye.xingchen]

From: ye xingchen <ye.xingc...@zte.com.cn>

Follow the advice of the Documentation/filesystems/sysfs.rst and show()
should only use sysfs_emit() or sysfs_emit_at() when formatting the
value to be returned to user space.
