This isn't how to use the device tree.  That is, you *aren't* using  
the device tree.  You want to read the node of every device you want  
to set up, and create the mapping.  Look at irq_of_parse_and_map().   
Look in include/asm-powerpc/prom.h, at of_irq_to_resource(), which  
maps an irq in the device tree.
