Bluetooth: Acquire wakelock to turn on lcd during Connection

This patch acquires wakelock to turn on LCD display of DUT if screen
is off during connection access request for PBAP/MAP. Without this
patch it was observed that if screen was off, lcd remained off for
incoming connection access request from remote device and user only
was hearing notification sound without lcd being lit up.

settings: Move headset option, hide MoreDeviceSettings if empty

 * This option fits much better in the sound menu under "automation
   and effects", and on many devices it's the only option in the
   "More..." menu under Tap & Pay.
 * Move it, and remove the MoreDeviceSettings top-level category if
   there's nothing else in it.
