Subject: [PATCH drm-misc-next v3 7/7] drm/arm/hdlcd: remove calls to drm_mode_config_cleanup()

drm_mode_config_init() simply calls drmm_mode_config_init(), hence
cleanup is automatically handled through registering
drm_mode_config_cleanup() with drmm_add_action_or_reset().

While at it, get rid of the deprecated drm_mode_config_init() and
replace it with drmm_mode_config_init() directly.
