From: Rafał Miłecki <rafal@xxxxxxxxxx>
So far wiphy's device had to be set using separated set_wiphy_dev call.
Most drivers were doing this right after calling wiphy_new anyway so
this just simplifies the code a bit.
The real advantage of this however is having access to struct dev during
early wiphy init. This allows e.g. reading extra DT info thanks to
of_node reference. It's important for things that may happen before
wiphy_register like custom regulatory.
