some restrictions for the sat setup

we don't allow
- DVB-S tuner ==loopthrough==> DVB-S2 tuner
- tuner A ==equals to==> tuner B set to loopthrough
- tuner A ==equals to==> tuner B set to 2nd cable on positioner LNB
- tuner A ==2nd cable==> tuner B, if tuner B is already referenced in another tuner's config as 2nd cable on this positioner
