drm/vmwgfx: Fix the driver for large dma addresses
commit 0d00c488f3de59d19784d5ce774528acaa194525 upstream.
With dma compliance / IOMMU support added to the driver in kernel 3.13,
the dma addresses can exceed 44 bits, which is what we support in
32-bit mode and with GMR1.
So in 32-bit mode and optionally in 64-bit mode, restrict the dma
addresses to 44 bits, and strip the old GMR1 code.
