This driver fist makes an expensive DT lookup to retrieve its DT node (this is a PCI driver) in order to later search for the base-mac-provider property. This property has no reality upstream and this code should not have been accepted like this in the first place. Instead, there is a proper nvmem interface that should be used. Let's avoid these extra lookups and rely on the nvmem internal logic.
