[PATCH] v4l: CX88 Update

- Removed unused structures.
- Removed BTTV version check.
- Some debug structs moved to their own .c file and converted to static
- Comment changed to express better when attach_inform is running
- set_freq removed from set_mode at tuner-core.c.
- I2C cleanups and converged to a basic reference structure.
- Rename tuner structures fields.
- It calls VIDIOC_G_FREQUENCY to get tuner freq from tuner.
- added missing contrast offset value, set to 0.
- Let Kconfig decide whether to include frontend-specific code.
