dms: new 'DMS Set FCC Authentication' message

Dell-branded Sierra modems, like the Dell DW5570 (Sierra Wireless MC8805) need
this specific command before they can be put in 'online' mode:

$ sudo qmicli -d /dev/cdc-wdm1 --dms-get-operating-mode
[/dev/cdc-wdm1] Operating mode retrieved:
	Mode: 'low-power'
	HW restricted: 'no'

$ sudo qmicli -d /dev/cdc-wdm1 --dms-set-fcc-authentication
[/dev/cdc-wdm1] Successfully set FCC authentication

$ sudo qmicli -d /dev/cdc-wdm1 --dms-get-operating-mode
[/dev/cdc-wdm1] Operating mode retrieved:
	Mode: 'online'
	HW restricted: 'no'
