panfrost: Probe G31/G52 if PAN_MESA_DEBUG=bifrost
We're not *quite* ready to open the flood gates on Bifrost (a major
blocker is CI, which is itself blocked on the lockdowns - expected to be
resolved in the coming months..)
Nevertheless, let's add a debug option to probe on compatible Bifrost
devices to avoid keeping out-of-tree patches around.
