Allocate Xv buffers to GTT.
KMS doesn't have acceleration for upload to vram. memcpy/memmove to VRAM
directly is very slow (40M/s in benchmark) which causes visible problems
to video.
Allocating video buffer in GTT will give good performance (350-450M/s)
for memmove operation. This is nice performance boost for Xv under KMS.
