[PATCH v3 9/9] drm/rockchip: cdn-dp: Don't unregister audio dev when unbinding

[Jeffy Chen]

After snd_soc_unregister_codec, the dai link would remain bound to
the invalid codec. That would cause crashes after unbind dp driver.

Let's unregister audio codec when removing dp driver to prevent that.
