mac80211: add support for multiple wiphys behind a single device

The device path will be the same for the first phy. For all subsequent
phys, the path gets an extra +1, +2, ...
Move the code for converting path to phy and vice versa to a separate
library script shared by config detection code and the netifd wireless
handler script
