Aleksander Morgado 0ebf6d5da5 mbm: query supported modes to the modem with +CFUN=? 
We were trying to load the generic modes supported reported by either *CNTI=2 or
AT+WS46=?, so that then we could filter out the MBM-specific modes unsupported.

But, this may not be ideal, as both these two commands may fail:

    [mm-broadband-modem.c:1612] modem_load_supported_modes(): loading supported modes...
    [mm-port-serial.c:1237] mm_port_serial_open(): (ttyACM1) device open count is 3 (open)
    [mm-port-serial.c:1294] _close_internal(): (ttyACM1) device open count is 2 (close)
    [mm-port-serial-at.c:440] debug_log(): (ttyACM1): --> 'AT*CNTI=2<CR>'
    [mm-port-serial-at.c:440] debug_log(): (ttyACM1): <-- '<CR><LF>ERROR<CR><LF>'
    [mm-serial-parsers.c:364] mm_serial_parser_v1_parse(): Got failure code 100: Unknown error
    [mm-broadband-modem.c:1546] supported_modes_cnti_ready(): Generic query of supported 3GPP networks with *CNTI failed: 'Unknown error'
    [mm-port-serial.c:1237] mm_port_serial_open(): (ttyACM1) device open count is 3 (open)
    [mm-port-serial.c:1294] _close_internal(): (ttyACM1) device open count is 2 (close)
    [mm-port-serial-at.c:440] debug_log(): (ttyACM1): --> 'AT+WS46=?<CR>'
    [mm-port-serial-at.c:440] debug_log(): (ttyACM1): <-- '<CR><LF>ERROR<CR><LF>'
    [mm-serial-parsers.c:364] mm_serial_parser_v1_parse(): Got failure code 100: Unknown error
    [mm-broadband-modem.c:1494] supported_modes_ws46_test_ready(): Generic query of supported 3GPP networks with WS46=? failed: 'Unknown error'
    [mm-iface-modem.c:3974] load_supported_modes_ready(): couldn't load Supported Modes: 'Couldn't retrieve supported modes'

Instead, we'll ask the modem for the list of modes supported, and return that
directly.
