mediatek: filogic: Migrate wifi configuration device paths

Browse Source 
The device path to the devices changed. Migrate the wifi
configurations from the old path to the new one. This is needed to
migrate Wireless configurations from OpenWrt 23.05 to OpenWrt 24.10.

This script is based on these two files:
target/linux/ramips/mt7621/base-files/etc/hotplug.d/ieee80211/05-wifi-migrate
target/linux/qualcommax/ipq807x/base-files/etc/hotplug.d/ieee80211/05-wifi-migrate

Fixes: 0ef9274721 ("mediatek: filogic: move mt7981 on-SoC blocks to "soc" node in DT")
Fixes: https://github.com/openwrt/openwrt/issues/17174
Link: https://github.com/openwrt/openwrt/pull/17210
