firewire: introduce fw_driver.probe and .remove methods
FireWire upper layer drivers are converted from generic struct driver.probe() and .remove() to bus-specific struct fw_driver.probe() and .remove(). The new .probe() adds a const struct ieee1394_device_id *id argument, indicating the entry in the driver's device identifiers table which matched the fw_unit to be probed. This new argument is used by the snd-firewire-speakers driver to look up device-specific parameters and methods. There is at least one other FireWire audio driver currently in development in which this will be useful too. The new .remove() drops the unused error return code. Although all in-tree drivers are being converted to the new methods, support for the old methods is left in place in this commit. This allows public developer trees to merge this commit and then move to the new fw_driver methods.
