SSL BigSix support

[GitHub issues - opened <github@alsa-project.org>]

alsa-project/alsa-ucm-conf issue #575 was opened from melonexe:

The SSL BigSix doesn't seem to have a UCM as far as I can see, I've tried to follow the example set by the other devices but I can't seem to get the syntax right according to the output of: 

 alsaucm -c hw:2 dump text

ALSA lib parser.c:2021:(parse_master_file) Incompatible syntax 6 in USB-Audio.conf
ALSA lib main.c:1412:(snd_use_case_mgr_open) error: failed to import hw:2 use case configuration -22
alsaucm: error failed to open sound card hw:2: Invalid argument

I have included what I have done so far, if you could point me in the right direction to resolving the above error I would be extremely grateful. Thanks for your work on this project.

The SSL Big six is a 16 in 16 out Class compliant audio interface https://solidstatelogic.com/products/big-six?tab=documentsanddownloads
