ASoC: fsl_spdif: change IFACE_PCM to IFACE_MIXER

BugLink: https://bugs.launchpad.net/bugs/2097332

[ Upstream commit bb76e82 ]

As the snd_soc_card_get_kcontrol() is updated to use
snd_ctl_find_id_mixer() in
commit 897cc72 ("ASoC: soc-card: Use
snd_ctl_find_id_mixer() instead of open-coding")
which make the iface fix to be IFACE_MIXER.
