Please also define the two LEDs here with their corresponding (only)
pinctrl options for each of them, with 'status = "disabled";'. This
makes it easier for boards to make use of the Ethernet PHY leds by just
referencing the LED and setting the status to 'okay'.

Sorry Daniel, definitely no. The LEDs really are board specific.

Try to convince me otherwise, but for this one I really doubt that you can.

Cheers,
