[POWERPC] Add an optional device_node pointer to the irq_host
The majority of irq_host implementations (3 out of 4) are associated with a device_node, and need to stash it somewhere. Rather than having it somewhere different for each host, add an optional device_node pointer to the irq_host structure.
