ASoC: wcd9310: Add high impedance headphone detection support
If HPHL and HPHR have relatively high impedance, internal MBHC HPHL
trigger cannot trigger so results in headphone/headset detection
failure.
Utilize MIC trigger as well as HPHL trigger in order to detect headphone
and headset which have high impedance on headphone line.
