drm/sun4i: framebuffer: Set mode_config.normalize_zpos
Back when support for zpos was added in commit 47a05f4a68f9 ("drm/sun4i:
backend: Add support for zpos"), a custom atomic_check callback was also
added in commit b8f1230dd3bf ("drm/sun4i: framebuffer: Add a custom
atomic_check") to have a place to call drm_atomic_normalize_zpos().
Commit 49efffc7fbd4 ("drm: Add drm_mode_config->normalize_zpos boolean")
added drm_atomic_normalize_zpos() to the standard atomic_check function.
Set mode_config.normalize_zpos and drop the custom atomic_check
implementation, which at this point is just a simplified copy of the
standard one. The standard one also checks whether async updates are
valid and updates the self refresh state, but neither feature is
supported by this driver.
