[PATCH] drm/panfrost: Name scheduler queues after their job slots

[Adrián Larumbe]

Drawing from commit d2624d90a0b7 ("drm/panthor: assign unique names to
queues"), give scheduler queues proper names that reflect the function
of their JM slot, so that this will be shown when gathering DRM
scheduler tracepoints.
