net: phy: mdio-gpio: Add #defines for the GPIO index's
The GPIOs are described in device tree using a list, without names. Add defines to indicate what each index in the list means. These defines should also be used by platform devices passing GPIOs via a GPIO lookup table. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
