[PATCH] v4l: bttv i2c audio update 

This patch updates the i2c audio chip modules.  It improves the support
for tda9874x chips.  There are some bugfixes.  It also has alot of small
cleanups: switch some modules to new initialization, declare lots of
functions static, ...  which make the patch a bit large.
