Hi, it looks like the pl061 device is not declared "user creatable" so
it is unavailable from the CLI. As a sysbus device, QEMU is not aware,
in the abstract, of how to "connect" the device to other devices.

See the sysbus class initialization code for more detail:

However, It looks like these boards/devices create such a device:


If you want one on some other kind of machine, you'll need to write it
up yourself in the machine board code, but you didn't tell us what
version of QEMU you're using, what machine type you are trying to use, etc.
