Nouveau - Oct 2024 - [PATCH 1/2] drm: Move plane->{fb,old_fb,crtc} to legacy sub-structure

From: Ville Syrj?l? <ville.syrjala at linux.intel.com>

Hide the plane->fb/etc. footguns better by stashing them inside
a "legacy" sub struct.

Eventually maybe we could turn 'legacy' into a pointer
that only exists on legacy drivers to completely prevent
any abuse by atomic drivers...

Side note: _dpu_plane_set_danger_state() looks completely
broken.
