caif: Add debug connection type for CAIF.
Added new CAIF protocol type CAIFPROTO_DEBUG for accessing CAIF debug on the ST Ericsson modems. There are two debug servers on the modem, one for radio related debug (CAIF_RADIO_DEBUG_SERVICE) and the other for communication/application related debug (CAIF_COM_DEBUG_SERVICE). The debug connection can contain trace debug printouts or interactive debug used for debugging and test. Debug connections can be of type STREAM or SEQPACKET.
