net: phy: Add LED mode driver for Microsemi PHYs.
LED Mode: Microsemi PHY support 2 LEDs (LED[0] and LED[1]) to display different status information that can be selected by setting LED mode. LED Mode parameter (vsc8531, led-0-mode) and (vsc8531, led-1-mode) get from Device Tree. Signed-off-by: Raju Lakkaraju <Raju.Lakkaraju@microsemi.com> Signed-off-by: David S.
