ramips: mt7621: add migration script for WLAN PCI paths
PCI paths of the WLAN devices have changed between kernel 5.10 and 5.15;
migrate config so existing wifi-iface definitions don't break.
This is implemented as a hotplug handler rather than a uci-defaults script
as the migration script must run before the 10-wifi-detect hotplug handler.
based on b452af23a8602ebf7bfb0eb084383ecd595face5
migration was forgotten when device trees were adjusted in
