It is possible to select audio inputs via em28xx or via ac97 functions.
This patch allows configuring a board to use either one way.
It also do some cleanups at audio setup configurations.

We don't need to do a dbg_info during tda18271_attach anymore, since
the tda18271_get_id function will call dbg_info with the same information
and more.

Since there are a few vidioc_ functions that were exported, rename those
functions to bttv_ in order to avoid poluting namespace.
The other functions were also renamed, to standardize inside the driver.

Add module option 'alt_tuner' disabled by default.
When set to one, the dvb_frontend of HVR1800 will consist of:
s5h1409 demod + tda18271 tuner
When set zero (default), the dvb_frontend of HVR1800 will consist of:
s5h1409 demod + mt2131 tuner
If the tda18271 is used in digital mode, you will not be able to
tune an analog channel at the same time.

Rather than using a pointer, include struct analog_demod_ops directly
inside struct dvb_frontend. This will allow us to use dvb_attach in
the future, along with removing the need to check the ops structure
before having to check the pointer to the method being called.
