- Drop some more safe regs taht userspace shouldn't hit
- Constant base regs need relocs.  This allows us to use
constant buffers rather than the constant register file.
Also we don't want userspace to be able to set arbitrary
mc base values for the const caches.
- Track SQ_CONFIG so we know whether userspace is using
the cfile or constant buffers.

R6xx+ cards need to use the 3D engine to blit data which requires
quite a bit of hw state setup.  Rather than pull the whole 3D driver
(which normally generates the 3D state) into the DRM, we opt to use
statically generated state tables.  The regsiter state and shaders
were hand generated to support blitting functionality.  See the 3D
driver or documentation for descriptions of the registers and
shader instructions.
