It's been waiting a while, it got posted as a part of another series,
but I think I'd like to apply this by the end of the week if nobody
objects.

A note regarding OP_HDMI vs OP_HDMI_AUDIO: there is really no point in
going through the OP_HDMI other than bridging the HPD even to the HDMI
audio through the framework code. The bridge driver doesn't implement
atomic_check (on purpose), the mode_valid() check is also performed
against a fixed table of modes handled by the firmware.
