vfio: selftests: Keep track of DMA regions mapped into the device
Keep track of the list of DMA regions that are mapped into the device
using a linked list and a new struct vfio_dma_region and use that to add
{__,}to_iova() for converting host virtual addresses into IOVAs.
This will be used in a subsequent commit to map multiple DMA regions
into a device that are then used by drivers.
