Dave Airlie 6a7068b4ef drm/radeon/kms: attempt to avoid copying data twice on coherent cards. (v3) 
On coherent systems (not-AGP) the IB should be in cached memory so should
be just as fast, so we can avoid copying to temporary pages and just use it
directly.

provides minor speedups on rv530: gears ~1820->1860, ipers: 29.9->30.6,
but always good to use less CPU if we can.

v3: cleanup unneeded bits.
