create a file drivers/bluetooth/hci_3wire.c and start with BCSP as base.
In general you can do a driver that supports BCSP and 3-Wire at the same
time, but actually I really like to have two separate drivers. Try to
start from scratch and don't copy too much things. The second part is
adding support for 3-Wire to the hciattach program.
