Subject: [PATCH] backends: Only apply EDID-based tablet mapping heuristic on
 integrated devices

These are the ones attached to a display, thus they are the ones that may need
help from this heuristic. Non-integrated tablets (e.g. Intuos) will default to
the span of all monitors.

Fixes mapping of opaque tablets if a display-integrated tablet of the same
brand is also plugged in.
