Some SoCs, like Allwinner A83T, have to do additional cleanup when HDMI driver unloads. When using DW HDMI through DRM bridge API, there is no place to store driver's private data so it can be accessed in unbind function. Because of that, add deinit function which is called at the very end, so drivers can do a proper cleanup.
