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.
