<div class='commit-subject'>net: phy: Add LED mode driver for Microsemi PHYs.</div><div class='commit-msg'>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.
