since it seems the driver is getting closer to be ready,
lets merge this extra protocol identifier as a separate patch.

depends on the definition of "the driver". It requires
the gpio information from DT, so it depends on the new
serial bus. I still have to implement that and it has
the potential to trigger a bit of discussion :)

Anyways I will split this out into its own patch later. 

Then we can adapt btattach as well for it.

It's enough to set ldisc=N_HCI and proto=HCI_UART_NOKIA.
Everything else is done by the protocol driver. I still
think it should be done from the kernel and will try to
come up with something in the serial bus.
