drm/radeon: Disable dma rings for bo moves on r6xx

Browse Source 
commit aeea40cbf9 upstream.

They still seem to cause instability on some r6xx parts.
As a follow up, we can switch to using CP DMA for bo
moves on r6xx as a lighter weight alternative to using
the 3D engine.

A version of this patch should also go to stable kernels.
