iommu/amd/pgtbl_v2: Invalidate updated page ranges only

Browse source

Enhance __domain_flush_pages() to detect domain page table mode and use
that info to build invalidation commands. So that we can use
amd_iommu_domain_flush_pages() to invalidate v2 page table.

Also pass PASID, gn variable to device_flush_iotlb() so that it can build
IOTLB invalidation command for both v1 and v2 page table.
