Let CPU/BSP Fatal handler have access to source

Without the source the error code does not say that much.
Let it be up to the CPU/BSP to determine the error code
reported on fatal shutdown.

This patch does not change the current behaviour, just
adds the option to handle the source of the fatal halt.
