drm/ingenic: Add ingenic_drm_bridge_atomic_enable and disable

Browse source

ingenic_drm_bridge_atomic_enable allows the CRTC to be enabled after
panels have slept out, and before their display is turned on, solving
a graphical bug on the newvision nv3502c.

Also add ingenic_drm_bridge_atomic_disable to balance it out.
