Subject[200/262] drm/radeon/kms: Add MSI quirk for HP RS690
3.0-stable review patch.  If anyone has any objections, please let me know.

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

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

commit b362105f7f5223fa4d2e03ceeea0e51da754ccc6 upstream.

Some HP laptops only seem to work with MSIs. This
looks like a platform/bios bug.

Fixes:
