drm/radeon/kms: disable hdmi audio by default
The current RE'd code causes blank screens and
display problems on a lot of systems. So disable
it by default for now. It can still be enabled
by setting the audio parameter to 1. E.g.:
radeon.audio=1

I'm not aware of an initiative to quirk on a per hardware basis enabling
hdmi audio by default. It seems this was preventative as too many
collateral damage reports were being filed with it enabled. The
WORKAROUND is now explicitly documented in
https://help.ubuntu.com/community/RadeonDriver .
Given this, what would you like the end game for this report to be?
