Subject: [ 57/73] drm/radeon: fix hdmi mode enable on RS600/RS690/RS740

3.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Deucher <alexander.deucher@....com>

commit dcb852905772416e322536ced5cb3c796d176af5 upstream.

These chips were previously skipped since they are
pre-R600.
