Subject: vfio/pci: Add driver_managed_dma to the new vfio_pci drivers
Git-commit: c490513c818d1ec61aff1614f5d0e38de680665f
Patch-mainline: v5.19-rc1
References: bsc#1205701
When the iommu series adding driver_managed_dma was rebased it missed that
new VFIO drivers were added and did not update them too.
Without this vfio will claim the groups are not viable.
Add driver_managed_dma to mlx5 and hisi.
Fixes: 70693f470848 ("vfio: Set DMA ownership for VFIO devices")
