[PATCH] v4l: common part Updates and tuner additions
- Remove $Id CVS logs for V4L files
- Included newer cards.
- Added a new NEC protocol for ir based on pulse distance.
- Enable ATSC support for DViCO FusionHDTV5 Gold.
- Added tuner LG NTSC (TALN mini series).
- Fixed tea5767 autodetection.
- Resolve more tuner types.
- Commented debug function removed from mainstream.
- Remove comments from mainstream. Still on development tree.
- linux/version dependencies removed.
- BTSC Lang1 now is set to auto_stereo mode.
- New tuner standby API.
- i2c-core.c uses hexadecimal for the i2c address, so it should stay consistent.
