firewire: ohci: do not bind to Pinnacle cards, avert panic
[ upstream commit 7f7e37115a8b6724f26d0637a04e1d35e3c59717 ]
When firewire-ohci is bound to a Pinnacle MovieBoard, eventually a
"Register access failure" is logged and an interrupt storm or a kernel
panic happens. https://bugzilla.kernel.org/show_bug.cgi?id=36622
Until this is sorted out (if that is going to succeed at all), let's
just prevent firewire-ohci from touching these devices.
