This will be used by the modesetting driver to support DRI2 across all
hardware that can support glamor, and could potentially be used by
other drivers that have to support DRI2 on sets of hardware with
multiple Mesa drivers.
This logic is the same as what's present in the Mesa driver loader,
except for the lack of nouveau_vieux support (which requires a
predicate on the device).
v2: Fix duplicated assignment of info->driverName.
