drm/panfrost: show device-wide list of DRM GEM objects over DebugFS
This change is essentially a Panfrost port of commit a3707f53eb3f
("drm/panthor: show device-wide list of DRM GEM objects over DebugFS").
The DebugFS file is almost the same as in Panthor, minus the GEM object
usage flags, since Panfrost has no kernel-only BO's.
Two additional GEM state flags which are displayed but aren't relevant
to Panthor are 'Purged' and 'Purgeable', since Panfrost implements an
explicit shrinker and a madvise ioctl to flag objects as reclaimable.
