[PATCH RFC] dvb: af9035.c: Logilink vg0022a to device id table

[Andreas Kemnade]

Ths adds the logilink VG00022a dvb-t dongle to the device table.
The dongle contains (checked by removing the case)
IT9303
SI2168
  214730

The result is in cold state:

so firmware uploading to the si2168 somehow messes things up

with some fixes in af9035.c I already get the same state as with warm
up by win7. I just need to find out which changes are really necessary
and convert it into a clean patch.

I experimented a lot here and I found this:
If 0101 is not sent to the si2168 you can get answers from the
Si2147-A30. 
After the 0101 is sent to the si2147-A30 it will still execute
commands but you will not get the answer back through the si2168.
You just get ff.

After moving the chip id readout from si2157_init to si2157_probe,
scanning for stations works. So the si2147-A30 seems to react on
commands.
