Subject: [PATCH v2 0/3] iommu: Retire detach_dev callback

Hi folks,

This is a follow-up series after several discussions on blocking domain.
The latest discussion could be found here.

https://lore.kernel.org/linux-iommu/20220510140238.GD49344@nvidia.com/

As .detach_dev equals to setting the blocking domain to the device, this
callback is not needed anymore. This replace .detach_dev callback in the
IOMMU drivers with a static blocking domain and retires this callback.

With .detach_dev retired, rename .attach_dev to .set_dev as it actually
means setting an iommu domain to the device.

This series depends on below series which includes blocking domain
support for VT-d and SMMUv3 drivers.

Please review and suggest.
