drm/nouveau: enable the ttm dma pool when swiotlb is active V3
If the card is capable of more than 32-bit, then use the default
TTM page pool code which allocates from anywhere in the memory.
Note: If the 'ttm.no_dma' parameter is set, the override is ignored
and the default TTM pool is used.
V2 use pci_set_consistent_dma_mask
V3 Rebase on top of no memory account changes (where/when is my
delorean when i need it ?)
