[ Upstream commit 17955aba7877a4494d8093ae5498e19469b01d57 ]
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.")
