ASoC: wcd9xxx: Handle anc headphone detection with slow insertion

When 4 pole/5 pole/6 pole headsets are inserted into jack with
anc support, we need to handle cases of slow insertions as it
might lead to incorrect detection. Reconfirm the plug type in this
case if anything other than headset is found.
