Subject: [PATCH 3/6] drm/virtio: Use drm_atomic_helper_buffer_damage_merged() for buffer damage

The driver does per-buffer uploads. It needs to use the damage helper that
handles buffer damages, rather than the helper that handles frame damages.

Fixes: 01f05940a9a7 ("drm/virtio: Enable fb damage clips property for the primary plane")
Cc: <stable@...r.kernel.org> # v6.4+
Reported-by: nerdopolis <bluescreen_avenger@...izon.net>
Closes: https://bugzilla.kernel.org/show_bug.cgi?id=218115
