drm/rockchip: logo: call bridge mode_set helper in rockchip_drm_show_logo

Browse Source 
drm_bridge require a display mode which pass through by calling
mode_set hooks, but mode_set only be called after setting mode_changed
flags, so call bridge->funcs->mode_set once in advance during kernel
logo which will not setting mode_changed flags.
