Audio:fix music playing through speaker instead of the headset when reboot DUT

1.if we insert wired headset and reboot DUT,it will playback by speaker instead of headset.
  It reason is lineout_gpio pin will be detected earlier than it is enabled and requested
  at initial boot,so it will detect wrong status to debug board.
  In this situation lineout_gpio is 0 when detection work at initial boot.
2.Modify lineout_gpio is enabled and requested earlier than detection work.
  we can improve this issue.
