net: phy: Add a binding for PHY LEDs
Define common binding parsing for all PHY drivers with LEDs using
phylib. Parse the DT as part of the phy_probe and add LEDs to the
linux LED class infrastructure. For the moment, provide a dummy
brightness function, which will later be replaced with a call into the
PHY driver. This allows testing since the LED core might otherwise
reject an LED whose brightness cannot be set.
Add a dependency on LED_CLASS. It either needs to be built in, or not
enabled, since a modular build can result in linker errors.
