iommu/vt-d: Remove aux-domain related callbacks
iommu: Remove aux-domain related interfaces and iommu_ops
iommu: Remove apply_resv_region
drm/nouveau/device: Get right pgsize_bitmap of iommu_domain
iommu: Use right way to retrieve iommu_ops
iommu: Remove unused argument in is_attach_deferred
iommu: Use dev_iommu_ops() helper
iommu: Split struct iommu_ops

Really cool, thanks for doing this, Baolu! I am currently running some
tests on this series to make sure there are no build breakages. And I
agree with Jason that:

iommu: Use right way to retrieve iommu_ops and
iommu: Use dev_iommu_ops() helper

can be combined into one patch. Splitting iommu_ops was something I have
been thinking about for some time, so thanks again for doing this.

You are welcome!

Do you want me to send a new version with below changes:

- Remove WARN_ON() in dev_iommu_ops();
- Merge above two patches.

Or, you can change above yourself?
