wlan: Add sysfs entry for BT profile indication 

Add the sysfs entry for the BT profile indication with two
parameters profile and profile mode.
    --> echo <BT_PROFILE> <PROFILE_MODE> > /sys/kernel/wlan/bt_profile
    where BT_PROFILE: BT_PROFILE_MAX, BT_PRPFILE_SCO etc
          MODE      : ENABLE/DISABLE
    f.e: echo  BT_PROFILE_MAX ENABLE > /sys/kernel/wlan/bt_profile
