Radxa-e52c. Device NIC port rename to match device labels and network LED config via radxa-e52c.conf (#8633)

* Add_to_radxa-e52c.conf

1. Add a network rule to rename interfaces to match device port labeling (wan,lan)

2. Add network activity LEDs config for wan and lan for radxa-e52c

* Update config/boards/radxa-e52c.conf

Coderabbitai suggested clean-up of function name.
