The FSL MSI code keeps a pointer to the of_node from the device
it represents. However it also has an irq_host, which contains
a pointer to the of_node, so use that one instead.

Hi Paul, I sent these a while ago, and they were acked by FSL folks and
Ojn - so I think Benh just forgot to merge them for 27.
