lan78xx: Read LED states from Device Tree Add support for DT property "microchip,led-modes", a vector of zero to four cells (u32s) in the range 0-15, each of which sets the mode for one of the LEDs. Some possible values are: 0=link/activity 1=link1000/activity 2=link100/activity 3=link10/activity 4=link100/1000/activity 5=link10/1000/activity 6=link10/100/activity 14=off 15=on These values are given symbolic constants in a dt-bindings header. Also use the presence of the DT property to indicate that the LEDs should be enabled - necessary in the event that no valid OTP or EEPROM is available.
