[PATCH 1/4] drm/radeon/radeon_audio: Remove unused r600_hdmi_audio_workaround

[linux@treblig.org]

From: "Dr. David Alan Gilbert" <linux@treblig.org>

The last use of r600_hdmi_audio_workaround() was removed by 2014's
commit 6e72376dcc66 ("radeon/audio: consolidate audio_mode_set()
functions")

Remove it.
