Using phys_page_find to translate an AddressSpace to a MemoryRegionSection is unwieldy. It requires to pass the page index rather than the address, and later memory_region_section_addr has to be called. Replace memory_region_section_addr with a function that does all of it: call phys_page_find, compute the offset within the region, and check how big the current mapping is. This way, a large flat region can be written with a single lookup rather than a page at a time. address_space_translate will also provide a single point where IOMMU forwarding is implemented.
