Thomas Hellstrom d92d985177 drm/vmwgfx: Use the linux DMA api to get valid device addresses of pages ...

The code handles three different cases:
1) physical page addresses. The ttm page array is used.
2) DMA subsystem addresses. A scatter-gather list is used.
3) Coherent pages. The ttm dma pool is used, together with the dma_ttm
array os dma_addr_t
