Add a new function load_image_mr(), which behaves like load_image_targphys() except that it loads the ROM image to a specified MemoryRegion rather than to a specified physical address. This is useful when a ROM blob needs to be loaded to a particular flash or ROM device but the address of that device in the machine's address space is not known. (For instance, ROMs in devices, or ROMs which might exist in a different address space to the system address space.)
