V4L/DVB (11682): STV0900/STV0903: Add support for Silicon cut >= 3

1. Support Silicon Cut >= 3.0
2. Remove support for obsolete cuts: 1.0. 1.1. 1.2
3. Try to catch more error cases

Driver doesn't now attach to obsolete silcon cuts, It just simply quits.
Results in code simplification, with removal of the obsolete cuts.
