[PATCH] macintosh: windfarm: Another convert to using %pOFn instead of device_node.name

[Rob Herring]

In preparation to remove the node name pointer from struct device_node,
convert printf users to use the %pOFn format specifier.

Convert the open coded iterating thru child nodes to
for_each_child_of_node() while we're here.
