TB16 Dock Linux Support

TBH I don't remember. I recently wiped my home folder and lost my notes from when I was running this.

When you run 

```sudo fwupdmgr get-devices```

You should get the following four devices for the TB-16, so I've listed the firmware I have for mine so they match with yours or are all of them showing as 0.0.0.0 then?


Dell TB16 Thunderbolt Cable
 Version:              0.0.3.18

Dell TB16 Port Controller 1
 Version:              0.1.2.17

Dell TB16 Port Controller 2
 Version:              0.1.2.50

Dell TB16
 Version:              0.0.0.0

Thanks for your reply. 

'fwupdmge get-devices' - I didn't need to use 'sudo' - gives me: 

Dell TB16, Current Version 0.0.0 

Dell Thunderbolt Cable, Current Version 16.00

Dell Thunderbolt Dock, Current Version 16.00

Dell TB16 Port Controller 1, Current Version 1.2.17

Dell TB16 Port Controller 2, Current Version 1.2.50

Dell TB16 Port Thunderbolt Cable, Current Version 0.3.18

So my versions seem to be the same as yours, which gives me a lot of comfort.  I don't know whether these are the versions it came with (in November 2017), or whether they've been updated automatically without my realising.  (I wouldn't have been aware of fwupdmgr until fairly recently.)  It would be helpful if the DELL TB16 support page could list what the latest versions should be.  

Many thanks and regards
