arm64: dts: lx2162a-clearfog: set sfp connector leds function and source

LX2162A Clearfog has four LEDs attached physically to the 4-port SFP
connector. They are intended to show information relating to network
interface status.

Select "netdev" as default trigger for each LED, and link each one to
the respective dpmac instance as trigger-source.
