Now that all drivers are using domain_alloc_paging() and dev is never NULL, we can have all drivers correctly set domain.pgsize_bitmap during their allocation function. There are a few oddities that have accumulated here over past changes: - Some drivers always set domain.pgsize_bitmap during their domain_alloc_paging() call but still provide a value in ops. This is dead code, delete it. - Some drivers calculate a system global pgsize_bitmap in the ops, but it is now trivial to use the per-instance value instead. In several cases this is dead code, delete it. This also allows constifying the ops in these drivers as a hardening measure - Some drivers have a fixed pgsize_bitmap, put it next to setting up the geometry in their domain_alloc_paging() functions. - Finally a few drivers still use ops because they have a delayed finalize operation. Set the constant pgsize_bitmap in the domain_alloc_paging(). Then remove ops.pgsize_bitmap. This is based on iommu next, and must go after the virtio domain_alloc_paging() conversion.
