net: phy: Manual remove LEDs to ensure correct ordering

If the core is left to remove the LEDs via devm_, it is performed too
late, after the PHY driver is removed from the PHY. This results in
dereferencing a NULL pointer when the LED core tries to turn the LED
off before destroying the LED.

Manually unregister the LEDs at a safe point in phy_remove.
