This adds debug printks for asynchronous transmission and reception and
for self ID reception.  They can be enabled at module load time, and at
runtime via /sys/module/firewire_ohci/parameters/debug.

Also added:  Logging of interrupt event codes and of cancelled AT
packets.

The code now depends on a Kconfig variable.  This makes it easier to
build firewire-ohci without the feature or to make it an option in the
future.  The variable is currently hidden and always on.

This feature inflates firewire-ohci.ko by 7 kB = 27% on x86-64 and by
4 kB = 23% on i686.

fw_core_handle_bus_reset() incorrectly relied on the assumption that
self_id_count > 0.

We check early in fw-ohci and discard the self ID complete event if
self_id_count == 0 because a valid event always has at least one self ID
packet in it (the one of the local node).  Hence treat self_id_count ==
0 like any other kind of invalid self ID buffer.

Try to write dual-phase retry protocol limits to BUSY_TIMEOUT register.
- The dual-phase retry protocol is optional to implement, and if not 
  supported, writes to the dual-phase portion of the register will be
  ignored. We try to write the original 1394-1995 default here.
- In the case of devices that are also SBP-3-compliant, all writes are 
  ignored, as the register is read-only, but contains single-phase retry of
  15, which is what we're trying to set for all SBP-2 device anyway, so this
  write attempt is safe and yields more consistent behavior for all devices.

See section 8.3.2.3.5 of the 1394-1995 spec, section 6.2 of the SBP-2 spec,
and section 6.4 of the SBP-3 spec for further details.

These drivers don't need to match any unit_directory type device.
They just need the id_table for module autoloading per module alias.

Not binding any of these drivers allows special-purpose drivers with
similar or same IDs to bind to devices.  This currently only benefits
out-of-tree drivers; on the other hand it is in no way detrimental to
in-tree drivers.

The num_interrupt_in, num_bulk_in, and other checks in the usb-serial
code are just wrong, there are too many different devices out there with
different numbers of endpoints.  We need to just be sticking with the
device ids instead of trying to catch this kind of thing.  It broke too
many different devices.

This fixes a large number of usb-serial devices to get them working
