V4L/DVB: tm6000+audio
I rework my last patch for audio and now audio works well. This patch
can be submited to GIT tree Quality of audio now is good for SECAM-DK.
For other standard I set some value from datasheet need some tests.
1. Fix pcm buffer overflow
2. Rework pcm buffer fill method
3. Swap bytes in audio stream
4. Change some registers value for TM6010
5. Change pcm buffer size
