[PORT FROM R2]audio: mfld_machine: Increased the wake lock duration from 1 second to 2 seconds

BZ: 22014

If frequent jack insertion/removal is done when phone is in S3 state, jack
events are reported by ALSA but they are not propagated to Andriod due to
hardcoded delay of 1 second in the HeadsetObserver before sending the intent.
But phone goes back to S3 state in 1 second, so intent is sent only when phone
wakes up.

Increased the wake lock duration to 2 seconds because duration of 1 second was
not sufficient.
