Currently driver sends fc interrupt id to FW instead of using
cpu interrupt id. We intend to fix that and keep backward
compatibility by using the same interrupt values.

To be able to debug long-running CS better, without changing the
userspace code, we are adding a new option through debugfs interface
to skip the reset of the device in case of CS timeout.
