The current watchdog API suggests that the pretimeout "allows Linux
to record useful information (like panic information and kernel
coredumps) before it resets". The call to panic() would be the
means to make this happen.

Now that I think about it, that does make sense.

However, if a pre-timeout is not set, then the driver should never call panic(). That means that the interrupt handler should only be registered if sbsa_gwdt_set_pretimeout() is called.
