ASoC: rt286: don't turn off HV and VREF if headset is detected
"HV" and "VREF" will be powered up when jack type detection process is started and will be powered off when jack type detection process is finished. It will generate an unexpected interrupt signal when they are powered up during the capture process. Codec driver will do the jack type detection process and we can't capture properly before the jack detection process is finished. This patch will not power off the "HV" and "VREF" widgets if headset is detected and it will solve the unexpected interrupt issue. As a result, it will also solve the silence data captured at the beginning in headset mic recording issue.
