vmwgfx: Reduce system resource usage with textured video
Use U and V textures and corresponding dma buffers that match
the size of the input UV data rather than using textures and DMA buffers
that match the Y data. This simplifies data copy and reduces the amount of
image data transfered to the host by up to 50% (YV12).
It also reduces dma buffer- and surface memory usage correspondingly.
