Subject: [PATCH 1/3] dt-bindings: net: Add dp83867 LED mode constants

These values reflect the register settings of LEDCR1, which maps PHY
status signals to LED pins.

This is the first of three patches that adds led configuration support
to the TI DP83867 driver. The DP83867 PHY has four LED output pins
(three of which are dedicated pins, one is muxed) whose functions are
configurable. To let system designers statically configure the LED
output functions, a devicetree property "ti,led-modes" is added. The
four entries of ti,led-modes correspond to the four LED settings in the
LEDCR1 register of the PHY.

The new led_modes field of dp83867_private is initialized only if
CONFIG_OF_MDIO is set. This is consistent with how all other fields of
that structure are currently initialized (e.g. tx_id_delay).
