* create_unimplemented_device: create and map a dummy device
* @name: name of the device for debug logging
* @base: base address of the device's MMIO region
* @size: size of the device's MMIO region
* This utility function creates and maps an instance of unimplemented-device,
* which is a dummy device which simply logs all guest accesses to
* it via the qemu_log LOG_UNIMP debug log.
* The device is mapped at priority -1000, which means that you can
* use it to cover a large region and then map other devices on top of it
* if necessary.
