From: Grant Likely <grant.lik...@secretlab.ca>
The MPC5200 internal interrupt controller setup function needs to set
the default interrupt controller when it is called. Without this
irq_create_of_mapping() cannot be called without first determining
the pointer to the irq controller (ie. call with controller = NULL).
