>> Add ethernet-phy nodes and specify phy interrupt (connected to pin PB25)
>> and board specific timing configs.
>>
>> Atmel has two different HW designs for its CPU modules: the first one
>> (produced by Embest) is connecting PHYAD[0-2] pins to pull up resistors
>> and the other one (produced by Ronetix) is connecting PHYAD0 to a pull up
>> resistor and PHYAD[1-2] to pull down resistors.
>> As a result, Ronetix design will have its PHY available at address 0x1 and
>> Embest design at 0x7.
>> By defining both phys we're letting the phy core detect the one actually
>> available on the MDIO bus.
