Johan Hovold 20bbc1e187 virtio-mmio: fix device release warning on module unload 
commit c687bc3569 upstream.

Driver core expects devices to be allocated dynamically and complains
loudly when a device that lacks a release function is freed.

Use __root_device_register() to allocate and register the root device
instead of open coding using a static device.

Note that root_device_register(), which also creates a link to the
module, cannot be used as the device is registered when parsing the
module parameters which happens before the module kobject has been set
up.

Fixes: 81a054ce0b ("virtio-mmio: Devices parameter parsing")
