Instead of a single channel map, multiple channel maps can be provided
in a form of compound (array) to hw and null plugins. In null
get_chmap, the channel map corresponding to the current channels is
copied from the given channel maps.

These cards won't provide the channel maps from the driver itself
because of the dynamic routing. For simplicity, define chmaps in the
configurations, so that chmap querying of individual stereo streams
and combined multi streams works properly.

This patch adds a DSP patch to fix an spdif_bug on some Audigy2 cards.
It also does detailed identification of the capabilities of the sound
card so that the patch is only applied to the sound cards that really
need it.
