Actually it seems that for me to grab the interrupt number I have to do the
platform device creation in fsl_soc.c and call arch_init() instead of doing it
from fsl_add_bridge(). fsl_add_bridge() is called way too early and the mpic
interrupt mapping has not been setup yet for me to acquire the interrupt number
from of_interrupt_to_resource() call.
