x86/mm/p2m: stop checking for IOMMU shared page tables in mmio_order()

Now that the iommu_map() and iommu_unmap() operations take an order
parameter and elide flushing there's no strong reason why modifying MMIO
ranges in the p2m should be restricted to a 4k granularity simply because
the IOMMU is enabled but shared page tables are not in operation.
