powerpc/pasemi: Use of_root in pas_pci_init()
Currently in pas_pci_init() a reference to the root node is leaked due
to a missing of_node_put(). Instead just use of_root directly.
Note that converting to of_find_compatible_node(NULL, ...) would
not be entirely equivalent, because that would check the compatible
property of the root node, whereas using of_root skips checking the root
node and start the search at the first child of the root.
