[PATCH] drm/radeon/kms: set a default max_pixel_clock

[PATCH] drm/radeon/kms: set a default max_pixel_clock

[Dave Airlie]

From: Dave Airlie <airlied@redhat.com>

On some Power rv100 cards, we have no ATY OF table, but we have
no combios table either, and hence we refuse all modes on VGA-0
since we end up with a 0 max pixel clock.
