These patches only do anything if there is an LED subnode in the PHY
node in DT. So there should not be an changes by default.

If you have both 'marvell,reg-init' poking values into registers, and
describe the LEDs in DT, then i would expect some change in
behaviour. But no existing DT files do that.
