The 'fabric' is the thing that pulls all of snd-aoa together, this patch
adds the 'layout' or 'layout-id' fabric that keys off the 'layout-id'

if an i2sbus is present with a layout-id (exported in modalias) that it can
use.

Just from curiosity:  Does this work properly?
I remember that there was a deadlock when you call request_module()
during module probe.
