This adds a way for the IOMMU user to know how much a new table will use so it can be accounted in the locked_vm limit before allocation happens. This stores the allocated table size in pnv_pci_ioda2_get_table_size() so the locked_vm counter can be updated correctly when a table is being disposed. This defines an iommu_table_group_ops callback to let VFIO know how much memory will be locked if a table is created.
