firewire: fw-ohci: conditionally log busReset interrupts

Add a debug option to watch bus reset interrupt events.  Half of this
patch is taken from Jarod Wilson's first version of the JMicron fix.

BusReset interrupts are only generated if the respective module
parameter flag was set before the controller is being initialized.
Else we keep this event masked to reduce IRQ load in normal operation
and to avoid potential problems with buggy chips.

Note, this is unlike the other IRQ events whose logging can be enabled
any time after chip initialization.  This and the influence on what
interrupts the chip generates is why I added an extra flag for it.

Also, reorder the debug parameter flags according to their perceived
usefulness.
