By reorganizing the code that sets the CHB3DxC bits we can not only
simplify this code but also fix the bug where the CHB3D8C bit was not
reset when playing a stereo stream after a 7.1 stream.

When the ad1848/cs2431 is first being initialized, auto-calibration may not
be set causing a timeout waiting for it in snd_ad1848/cs4231_mce_down().
This has no dire consequences other than an alarming printk, but since what
we need to wait for is for the calibration to _finish_, let's just check for
that instead.
The early chips need a slight delay (as commented -- 5 sample periods) to be
sure that _if_ calibration is going to happen, it has started when we check
While the CS4231A datasheet implies it'll happen immediately on downing MCE,
some testing is showing that there's a window there as well, so just do the
delay everywhere.

Different cards have different audio configurations, but the driver didn't
support this.  The only setting it had was the digital rate.
This patch adds a board configuration list.  Currently, configurable items are
the digital rate and the digital data format (for cards with an external ADC),
a flag for the absence of an external ADC, and a flag for no connection to the
Bt87x internal ADC.
This allows cards that don't use the internal ADC to omit the ALSA 'Bt87x
analog' device and related controls.  Cards without an external ADC can omit
the 'Bt87x digital' device.
In order to support the CS5331A ADC used on the Osprey 440 and 2x0 cards, the
digital format needs to be different than the default.
Support could be added for defining:
  The connections or lack of them to the Bt87x's internal ADC mux
  Multiple sample rates for an external ADC (e.g. Osprey)
  Control of an external mux for an external ADC (e.g. Osprey)
The card definitions for cards other than the Ospreys are kept equivalent to
their old values.  This is likely inaccurate for most cards, as it is doubtful
that both an external and the internal ADC would be used.  Lacking information
on those cards, the behavior is left unchanged.
