[Qemu-devel] [PATCH] hw/core/register: Mark the device with cannot_instantiate_with_device_add_yet

[Thomas Huth]

The "qemu,register" device is just used internally. It's strange to
see this device showing up in the "-device ?" help text. Let's mark it
with cannot_instantiate_with_device_add_yet to hide it from the users.
