exec: extract address_space_translate_iommu, fix page_mask corner case

This will be used to process IOMMUs in a MemoryRegionCache.  This
includes a small bugfix, in that the returned page_mask is now
correctly -1 if the IOMMU memory region maps the entire address
space directly.  Previously, address_space_get_iotlb_entry would
return ~TARGET_PAGE_MASK.
