FWIW, this limits this driver to support a single device ever. We
can't bind multiple devices to this driver now. Yeah, perhaps we will
never be required to do so, but who knows.

Actually, I believe multiple devices really should be possible.

The major benefit of virtio-i2c is either bridging certan real bus'es
into a confined workload, or creating virtual hw testbeds w/o having to
write a complete emulation (in this case, for dozens of different i2c
controllers) - and having multiple i2c interfaces in one machine isn't
exactly rare.
