[ Upstream commit 50ebe56222bfa0911a932930f9229ee5995508d9 ]

A user of FFADO project reported the issue of ToneWeal FW66. As a result,
the device is identified as one of applications of BeBoB solution.

I note that in the report the device returns contradictory result in plug
discovery process for audio subunit. Fortunately ALSA BeBoB driver doesn't
perform it thus it's likely to handle the device without issues.

I receive no reaction to test request for this patch yet, however it would
be worth to add support for it.
