[ALSA] dynamic minors (3/6): store device-specific object pointers dynamically

Browse Source 
Instead of storing the pointers to the device-specific structures in an
array, put them into the struct snd_minor, and look them up dynamically.

This makes the device type modules independent of the minor number
encoding.
