Subject: drm/virtio: make drm_fb_helper_funcs const
Git-commit: 91b39a4e282cfd729bd8a279ec296eb6af398bec
Patch-mainline: v4.14-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Make these structures const as they are only passed to the function
drm_fb_helper_prepare and the corresponding argument is of type const.
Done using Coccinelle
