hotplug: Allow configuring radio name.

This way the radio (phy) name can be the same through module reloads.

To set the desired name:

uci set wireless.@wifi-device[0].phyname=wiphy0

I guess this only works on ipq6086 boards as I could not find a more
generic place to put this.  Maybe someone can improve it.
