hw/sysbus: Add sysbus_mmio_get_region()
Add a sysbus_mmio_get_region() which allows users of sysbus devices to turn a (SysBusDevice*, mmioidx) tuple into a MemoryRegion*. This enables some useful simplifications of devices which pass through another device's mmio region (either directly or by implementing some kind of memory controller device).
