IEEE-1394 Sync with r1088

- Cleanup Kconfig so that ieee1394 core doesn't require PCI.

- Some function renames to make things consistent.

- Fixup ISO API so that packet-per-buffer and irq-interval work
  correctly.

- Get rid of host list and use driver model for handling host ref count
  and host accounting.

- Get rid of packet semaphore.

- Move bus registration into core ieee1394 initialization.

- Get rid of ancient unused data_be (big-endian) flag in packet struct.

- Fix recursive use of bus_for_each_dev() in nodemgr.

- Revert changes to oui.db. This file is verbatim from IEEE, so if any
  changes should be made, register them with the IEEE database and keep
  this one pristine.

- Fix PCILynx so that it checks for errors on calls to copy_from_user().

- Add ARM API handlers to raw1394.

- Cleanup sbp2's packet sending to accomodate for a case where a packet
  was free'd while sbp2 was waiting on it.
