bccb3deee2 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.

fewer VBOs than vertex elements so this is a small win in itselfs, but
more importantly, the VFD_DECODE state now only depends on program
