This patch improves the panic/die notifiers in this driver by
making use of a passed "id" instead of comparing pointer
address; also, it removes an useless prototype declaration
and unnecessary header inclusion.
This is part of a panic notifiers refactor - this notifier in
the future will be moved to a new list, that encompass the
information notifiers only.
