drm/msm/dp: unregister audio driver during unbind
[ Upstream commit 85c636284cb63b7740b4ae98881ace92158068d3 ]
while binding the code always registers a audio driver, however there
is no corresponding unregistration done in unbind. This leads to multiple
redundant audio platform devices if dp_display_bind and dp_display_unbind
happens multiple times during startup. On X13s platform this resulted in
6 to 9 audio codec device instead of just 3 codec devices for 3 dp ports.
Fix this by unregistering codecs on unbind.
