ieee1394: pcilynx: I2C cleanups
* Delete optional and empty i2c client_register and client_unregister
callbacks.
* Use the proper i2c adapter ID.
* Don't use a template to initialize the i2c_adapter structure, it's
inefficient.
* Update a misleading comment on why we use i2c_transfer rather than
higher level i2c functions.
