These are no longer needed given that dma-buf is
now backported.

-Disable PRIME support in core drm, radeon, nouveau and i915 for
-kernels < 3.4.0.
-
-PRIME depends on dma-buf which is added to the kernel with 3.3 but
-the one in 3.3 is mostly stub, e.g. it is a skeleton API which
-is highly modified in 3.4. So disable PRIME for kernels < 3.4.0,
-not < 3.3.0.
