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.
