net: move devres helpers into a separate source file
There's currently only a single devres helper in net/ - devm variant of alloc_etherdev. Let's move it to net/devres.c with the intention of assing a second one: devm_register_netdev(). This new routine will need to know the address of the release function of devm_alloc_etherdev() so that it can verify (using devres_find()) that the struct net_device that's being passed to it is also resource managed.
