Panfrost DRM client usage stats implementation
The drm/Panfrost driver implements the DRM client usage stats specification as
documented in :ref:`drm-client-usage-stats`.
Example of the output showing the implemented key value pairs and entirety of
the currently possible format options:
pos: 0
flags: 02400002
mnt_id: 27

drm-shared-memory: 0 MiB
drm-active-memory: 226 MiB
drm-resident-memory: 36496 KiB
drm-purgeable-memory: 128 KiB
Possible `drm-engine-` key names are: `fragment`, and `vertex-tiler`.
`drm-curfreq-` values convey the current operating frequency for that engine.
