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.

P2P : Fix for P2P group name

When device is in Chinese language, P2P group SSID names will be encoded
into UTF-8 hex format. When displaying group SSID in UI Settings, this
UTF-8 should be converted back to UTF-8 binary format.
Implemented method to convert UTF-8 hex to UTF-8 binary format. When
group is created, it checks the hex format by looking '\x' sequence,
then converts to binary format.
