iommu/amd: Enhance amd_iommu_domain_alloc_user()
Previous patch enhanced core layer to check device PASID capability and
pass right flags to ops->domain_alloc_user().
Enhance amd_iommu_domain_alloc_user() to allocate domain with
appropriate page table based on flags parameter.
- If flags is empty then allocate domain with default page table type.
This will eventually replace ops->domain_alloc().
For UNMANAGED domain, core will call this interface with flags=0. So
AMD driver will continue to allocate V1 page table.
- If IOMMU_HWPT_ALLOC_PASID flags is passed then allocate domain with v2
page table.
