[PATCH] ASoC: fsl_micfil: Fix error handler with pm_runtime_enable

[Shengjiu Wang <shengjiu.wang@nxp.com>]

There is error message when defer probe happens:

fsl-micfil-dai 30ca0000.micfil: Unbalanced pm_runtime_enable!

Fix the error handler with pm_runtime_enable and add
fsl_micfil_remove() for pm_runtime_disable.

Fixes: 47a70e6fc9a8 ("ASoC: Add MICFIL SoC Digital Audio Interface driver.")
