The DisplayPort AUX channel gets initialized and registered during
dw_dp_bind(), but it is never unregistered, which may lead to resource
leaks and/or use-after-free.
Add the missing dw_dp_unbind() function to allow the users of the
library to handle the required cleanup, i.e. unregister the AUX adapter.
