Subject: [PATCH 2/3] drm/exynos: Convert to drmm_mode_config_init() and drop
 manual cleanup

Switch mode-config initialization to drmm_mode_config_init() so that the
lifetime is tied to drm_device. Remove explicit drm_mode_config_cleanup()
from error and unbind paths since cleanup is now managed by DRM.

No functional change intended.
