    mediatek: do not create device nodes in uci-defaults script
    
    Since commit 298814e6be76 ("base-files: config_generate: split macaddr with
    multiple ifaces") uci MAC address setup will create a device node for each
    member iface. But this script might override the device nodes and interfere
    with the MAC address setup.
