To add a bit of vendor flexibility with various virtio based devices, allow the caller to specify a different DMA mask. This adds a dma_mask field to struct virtio_pci_modern_device. If defined by the driver, this mask will be used in a call to dma_set_mask_and_coherent() instead of the traditional DMA_BIT_MASK(64). This allows limiting the DMA space on vendor devices with address limitations.
