[PATCH] v4l: I2C Tuner

- Fixed a trouble on tuner-core that generates erros on computers with more
  than one TV card.
- Rename tuner structures fields.
- Tail spaces removed.
- I2C cleanups and converged to a basic reference structure.
- Removed unused structures.
- Fix setting frequency on tda8290.
- Added code for TEA5767 autodetection.
- Standby mode support implemented. It is used to disable
  a non used tuner. Currenlty implemented on tea5767.
- New macro: set_type disables other tuner when changing mode.
- Some cleanups.
- Use 50 kHz step when tunning radio for most tuners to improve precision.
