Patrick Rudolph 4b7b18d14a console: Add weak method to notify about death
Call weak method die_notify.

The method should be overwritten in mainboard directory to signal that
a fatal error had occurred. On boards that do share the same EC and where
the EC is capable of controlling LEDs or a buzzer the method can be
overwritten in EC directory instead.

Tested on Lenovo T500.
