[PATCH v2 01/10] drm/panel/visionox-g2647fb105: Use refcounted allocation in place of devm_kzalloc()

[Albert Esteve <aesteve@redhat.com>]

Move to using the new API devm_drm_panel_alloc() to allocate the
panel. In the call to the new API, avoid using explicit type and use
__typeof() for more type safety. Also deduplicate the prepare_prev_first
assignment that was set both before and after drm_panel_init().
