drm/imx: replace struct drm_simple_display_pipe with regular atomic helpers
Convert i.MX LCDC to explicit primary plane, CRTC and encoder objects.
Keep no-scaling plane check and GEM framebuffer prepare callback from
simple-KMS path.
Wire the vblank lifecycle explicitly with CRTC vblank callbacks and
drm_crtc_vblank_on()/drm_crtc_vblank_off(). Use the old CRTC state in
the disable path for clock unwinding so the clock reference count
remains paired with the previous active state.
Use the atomic_create_state helpers with
drm_mode_config_create_initial_state() in probe, and
drm_crtc_vblank_atomic_flush() for the flush callback.
