nas: implement 'Get LTE Cphy CA Info'

Carrier aggregation is much more fun when you can watch it being
activated :)

$ qmicli -p -d /dev/cdc-wdm0   --nas-get-lte-cphy-ca-info
[/dev/cdc-wdm0] Successfully got carrier aggregation info
DL Bandwidth: '20'
Secondary Cell Info
        Physical Cell ID: '101'
        TX Channel: '3050'
        DL Bandwidth: '20'
        LTE Band: 'eutran-7'
        State: 'activated'
Primary Cell Info
        Physical Cell ID: '299'
        TX Channel: '1450'
        DL Bandwidth: '20'
        LTE Band: 'eutran-3'
Secondary Cell index: '1'

I have absolutely no clue about the required NAS version, so I just put
the current version I have there...
