[ Upstream commit 28108d71ee11a7232e1102effab3361049dcd3b8 ]

There is error message when defer probe happens:

fsl-spdif-dai 2dab0000.spdif: Unbalanced pm_runtime_enable!

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

Fixes: 9cb2b3796e08 ("ASoC: fsl_spdif: Add pm runtime function")
