[PATCH] v4l: tuner + tda9887 updates 

This is a big update for the tuner and tda9887 modules which are used for TV
card tuning.

The tda9887 module is basically completely rewritten and understands all the
config bits now instead of having just some fixed config presets.  Some of
these config bits can be changed by insmod options now.

The other big change is that both modules allow to use the V4L2 API for
inter-module communication (i.e.  when bttv/saa7134/...  pass through the
tuning ioctls to the modules).  That allows to specify the TV norm more
precisely (not just PAL but PAL-I, PAL-BG, ...), which is needed in some cases
to make TV audio work correctly.  Using the old v4l1 API is still possible so
this shouldn't break any users of these two modules.
