[ 096/133] drm/radeon: force MSIs on RS690 asics

[Greg Kroah-Hartman]

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

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

From: Alex Deucher <alexander.deucher@xxxxxxx>

commit fb6ca6d154cdcd53e7f27f8dbba513830372699b upstream.

There are so many quirks, lets just try and force
this for all RS690s.  See:
