MLK-12244 ASoC: fsl: Set the sound card owner field
When load sound card, the pulseaudio will using the sound card to
playback and record. It may be cause a kernel crash when the sound
card is unloaded while the playback/record is active
After setting the sound card owner field, when pulseaudio is running,
the sound card module ref-count will not be 0 and the sound card will
not be unloaded. So you should stop the pulseaudio when you want to
unload the sound card.
