Subject: [RFC PATCH 2/2] drm/panthor: register size of internal objects through fdinfo

This includes both DRM objects created to support queues, groups and heaps,
and also objects whose pages are shared between the GPU and the MCU.

However, this doesn't include objects that hold the firmware's binary
regions, since these aren't owned by a render context and are allocated
only once at driver's initialisation time.
