dms: new 'Foxconn Set FCC authentication' command

This command allows unlocking Foxconn-manufactured modules like the Dell-branded DW5821e (T77W968) or the new 5G-capable T99W175 module shipped in Lenovo Thinkpads. Without the unlock, the module cannot be put online (RF is kept off).

The command was found looking at a USB capture obtained from running the "Dell Custkit tool for the DW5821e/DW5829e" under Windows: 0x01, 0x10, 0x00, 0x00, 0x02, 0x01, 0x00, 0x01, 0x00, 0x71, 0x55, 0x04, 0x00, 0x01, 0x01, 0x00, 0x00
