alsa-profiles: use SB Audigy PCM mixer controls

Browse source 
Creative Labs Sound Blaster Audigy cards (snd_emu10k1 driver) expose
mixer controls named 'PCM Front', 'PCM Rear', etc. in addition to the
more common 'Front', 'Rear', etc.  The latter seem to be intended for
a stereo-to-all-speakers mirroring mode that we do not use, and have
no effect when we adjust them.
https://docs.kernel.org/sound/cards/audigy-mixer.html

We therefore define a custom mixer path for Audigy devices, using the
PCM mixer controls.

This has been tested on an Audigy 5/Rx.  Based on a brief look at the
ALSA driver, I think all Audigy devices (vendor 0x1102, device 0x0004
or 0x0008) have the same PCM controls, making this change probably safe
for our existing Audigy udev rules.
