Revert "ASoC: fsl: fix multiple definition of init_module"

This reverts commit 25b8d31488a3fb3611651991969526b2ea475764.

While the commit fixes multiple init_module definition error with
module build, it breaks build when both imx-pcm-fiq and imx-pcm-dma
are built in as below.

Let's revert the commit and find a proper fix for multiple init_module
definition error later.
