r600g: specialized upload manager
Allow important performance increase by doing hw specific implementation of the upload manager helper. Drop the range flushing that is not hit with this code (and wasn't with previous neither). Performance improvement are mostly visible on slow CPU. Signed-off-by: Jerome Glisse <[email protected]>
