ASoC: fsl-asoc-card: enable ignore_pmdown_time for ASRC case
Problem:
When switching from ASRC path (hw:0,1) to direct path (hw:0,0),
audio stops after 5 seconds due to DAPM powering down shared widgets.
Scenario:
1. Play on hw:0,1 (ASRC): ASRC-Playback → CPU-Playback → Codec
2. Stop playback
3. Play on hw:0,0 (Direct): CPU-Playback → Codec
4. After 5s: No sound (DAPM powered down CPU-Playback)
Root Cause:
DAPM sees ASRC-Playback disconnected and powers down the entire
path including CPU-Playback, even though CPU-Playback is still
needed for the direct path.
Solution:
Enable ignore_pmdown_time for DPCM links to prevent premature
widget power-down when switching between paths.
