We should try to have the DT parsing made generic in phylib, and add
new driver API calls to actually configure the LEDs.

Please also take a look at the Linux generic LED binding. It would be
nice to have something compatible with that. With time, the code could
morph into being part of the generic LED subsystem. So we are mostly
talking about triggers. But we offload the trigger to the hardware,
rather than have software trigger the blinking of the LEDs. So
something like:

ethernet-phy0  {
	reg = <0>;

	leds {
		phy-led@0 {
	     	      reg = <0>
		      label = "left:green";
		      linux,default-trigger = "phy_link_1000_active";
		}
		phy-led@1 {
	     	      reg = <1>
		      label = "right:red";
		      linux,default-trigger = "phy_collision";
		}
	}
}
