add support for multi phy devices
Such single device could create multiple phys:
root@OpenWrt:# ls /sys/devices/platform/soc/18000000.wifi/ieee80211/
phy0 phy1
root@OpenWrt:#
root@OpenWrt:# ls -l /sys/class/ieee80211/phy0/device
lrwxrwxrwx 1 root root 0 Aug 19 14:01 /sys/class/ieee80211/phy0/device -> ../../../18000000.wifi
root@OpenWrt:# ls -l /sys/class/ieee80211/phy1/device
lrwxrwxrwx 1 root root 0 Aug 19 14:01 /sys/class/ieee80211/phy1/device -> ../../../18000000.wifi
root@OpenWrt:~#
So, before we fail to find connect phyX base on radio name from UCI device section.
Code ported from iwinfo, where we have:
root@OpenWrt:/sys# iwinfo nl80211 path phy0 platform/soc/18000000.wifi root@OpenWrt:/sys#
