Introduce function mwifiex_probe_of() to parse common properties. Since the interface drivers get to decide whether or not the device tree node was a valid one (depending on the compatible property), let the interface drivers pass a flag to indicate whether the device tree node was a valid one. The function mwifiex_probe_of()nodetself is currently only a place holder with the next patch adding content to it.
