ASoC: Use pm_wakeup_event() in WM8962 jack detection

Ensure that the system does not suspend while we process a WM8962 jack
event by using pm_wakeup_event() to block the suspend while we're waiting
for the jack to settle. Use a slightly longer timeout than the jack waits
to allow for other stuff to take over and delays in scheduling.
