[PATCH v2 08/10] drm/panel/truly-nt35597: 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.
