[PATCH 08/10] drm/radeon/ttm: handle ttm moves properly

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

The core move code currently handles use_tt moves, for radeon
this was being handled also in the driver, but not using the same
paths.

If moving between TT/SYSTEM (all the use_tt paths on radeon) use
the core move function.

Eventually the core will be flipped over to calling the driver.
