Add the devices working with current drivers for the
Epson Moverio BT-200 AR glasses consisting of a control unit
and the glasses itself.

yes, epson,embt2ws is unknown, is the txt->yaml conversion around the
corner? I would then resubmit it includding an addition
to that yaml. If not probably I resubmit the conversion patch with
the compatible added. But that should not stop the rest of this patch from
being reviewed.
