Subject: [PATCH v4 0/3] drm/vkms: Switch to allocated for drm objects

Specific allocations for each DRM object is not strictly needed in VKMS
right now, but in order to implement dynamic configuration of VKMS
(configFS), it will be easier to have one allocation per DRM object.

There is no need for a dynamic allocation for the writeback connector as
there can only be one per CRTC

No functionnal changes are intented in this series.

This series requires [1] to switch vkms objects to drm-managed objects.
