Subject: [PATCH] drm: mxsfb: constify drm_simple_display_pipe_funcs

drm_simple_display_pipe_funcs are not supposed to change at runtime.
All functions working with drm_simple_display_pipe_funcs provided
by <drm/drm_simple_kms_helper.h> work with const
drm_simple_display_pipe_funcs. So mark the non-const structs as const.
