drm: Add helper to implement legacy dirtyfb
Add an atomic helper to implement dirtyfb support. This is needed to support DSI command-mode panels with x11 userspace (ie. when we can't rely on pageflips to trigger a flush to the panel). v2: Modified the helper to use plane fb_damage_clips property and removed plane_state::dirty flag. v3: - Use uapi drm_mode_rect. - Support annotate flags. v4: Correct kernel doc.
