rockchip: make NIC name predictable for LinkEase EasePi R1

The probe order for PCIe buses and devices is non-deterministic,
making the names eth2 and eth3 unpredictable (they may be swapped).

This patch fixes the names by referencing the device path using
`ucidef_set_network_device_path`.

This patch ensures that the OpenWrt interface name matches the case label.
