HDA is part of the DISP_USB bus, so move it into that and drop the
address prefix accordingly.

Is there a fixes-tag we need for this?

I think it'd be good if Sheetal could review and test it, at which point
I could equally well merge it into her initial patch that added this,
which is still very close to the top of the arm64/dt branch. Even if it
remains a standalone patch, no need for a Fixes: tag since it'll all go
into the same version anyway and doesn't need to be backported.
