Did some code reorganization: split up the source into four files:
 - tuner-core.c for all the interfacing stuff (register driver,
   handle insmod options, react on v4l ioctls, ...),
 - tuner-simple.c for all those trivial 4-byte-command-sequence tuner
   chips.
 - mt20xx.c for the mt2032 and mt2050 tuners.
 - tda8290.c for the tda8290/8272 combo (this code is new).

I also did a number of cleanups like using dev_printk() for the
messages everythere.  There should be no functional changes beside
the new support for the tda8290 tuner.
