powerpc/mpc5200: Make internal 5200 PIC the default interrupt controller

Browse Source 
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).
