[PATCH] v4l: bug fixes for tuner, cx88 and tea5767

- In CX88 code, some cards needs to have audio reprogramed after changing
  video channel;

- Tuner autodetection code seems not to work on some cards.  Now,
  no_autodetect insmod option allows disabling autodetection code;

- Minor fixes in tea5767 to reduce integer trunc;

- There are some new Pixelview Ultra Pro cards that doesn't use TEA5767
  for radio.  As autodetection is capable of checking for tea, radio tuners
  and addresses removed.

- CX88 version number incremented.
