macintosh: Use of_node_name_{eq, prefix} for node name comparisons
Convert string compares of DT node names to use of_node_name_{eq,prefix} helpers instead. This removes direct access to the node name pointer. This changes a single case insensitive node name comparison to case sensitive for "ata4". This is the only instance of a case insensitive comparison for all the open coded node name comparisons on powerpc. Searching the commit history, there doesn't appear to be any reason for it to be case insensitive. A couple of open coded iterating thru the child node names are converted to use for_each_child_of_node() instead.
