ASoC: cs42l43: Extend timeout on bias sense timeout

Browse Source 
For very slow removals the current bias sense timeout is sometimes too
short and unclamps the mic bias before the jack removal is properly
detected by the tip detect, causing a pop. As bias sense should be
tuned to deliver very few false positives, increase the timeout fairly
dramatically to cover all but the most exaggerated removals.
