Convert string compares of DT node names to use of_node_name_eq helper instead. This removes direct access to the node name pointer.

I applied the pci/of.c change to pci/misc for v5.1, thanks! I dropped the rpaphp_core.c part because there's another patch in-flight [1] that touches the same code, and it would be easier if Michael picked up this change and added it to his series.
