ep93xx-eth: check for zero MAC address on probe, not on device open 

If we happen to have registered the driver without passing
a MAC address, we will print a zero MAC address and register
the interface with this invalid address, this is confusin. This
patch moves the checking of a valid ethernet address and the
generation of a random one down from the open function to
the probe function.
