Thanks for the information. This sounds like a wake on LAN feature.
I've seen other Marvell hardware connect a PHY LED output pin to the
circuit controlling the main power supply. When the PHY detects the
magic wake-up packet, it 'blinks' the LED so turning the power back
on.

My guess is, the register write to the PHY is configuring the LED. Do
you have the datasheet for the PHY? Can you check this?

Once we understand what is going on here, we can consider adding
support for this.
