[PATCH] v4l: tuner improvements

Browse Source 
*tuner-core.c:
- some tuner_info msgs will be generated only if insmod opt
        tuner_debug enabled.
- Implemented tuner-core support for VIDIO_S_TUNER to allow
        changing mono/stereo mode
- Remove unneeded config options.
- I2C_CLIENT_MULTI option removed.
- support for Philips FMD12ME hybrid tuner
- allow to initialize with another tuner
- Move PHILIPS_FMD initialization code to set_type function,

* tda8290:

- Fix dumb error in tda8290 tunning.
- Radio tuner uses high-precision step instead of 62.5 KHz.

*tea5767.c:
- tuner_info msgs will be generated only if insmod tuner option
        tuner_debug enabled.
- some cleanups for better reading.
- Radio tuner uses high-precision step instead of 62.5 KHz.
- Changing radio mode stereo/mono for tea5767 working.

*tuner-simple.c:
- TNF9533-D/IF UHF fixup.
- Radio tuners now uses high-precision step instead of 62.5 KHz.

*mt20xx.c:
        - Radio tuner uses high-precision step instead of 62.5 KHz.

*tda9887.c:
        - tab and blank spaces corrections.
