While we're at it: could you submit the UCM profiles as alsa-lib
upstream?  At least the ones for the drivers that are in the current
kernel should be merged.

If there are multiple board-specific UCMs for the same driver, we can
use now card's longname (generated from DMI string) as the primary
source, while keeping the $DRIVER/$DRIVER.conf as the fallback.
