So now the sequence would be something like:
1)VFIO_GROUP_SET_CONTAINER // add groups to the container
2)VFIO_SET_IOMMU(VFIO_FSL_PAMU)// set iommu model
3)count = VFIO_IOMMU_GET_MSI_BANK_COUNT// returns max # of MSI banks
4)VFIO_IOMMU_SET_ATTR(ATTR_G

-v3 updates
-made vfio_pamu_attr a union, added flags
-s/VFIO_PAMU_/VFIO_IOMMU_PAMU_/ for the ioctls to make it more
clear which fd is being operated on
-added flags to vfio_pamu_msi_bank_map/umap
-VFIO_PAMU_GET_MSI_BANK_COUNT now just returns a __u32
not a struct
-fixed some
