Bluetooth: Move a2mp.h header file into net/bluetooth/
The a2mp.h header file is only used internally by the bluetooth.ko module and is not a public API. So make it local to the core Bluetooth module. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
