qemuzynq: Add fixed-clock to device tree for ethernet
* Add a fixed 125 MHz clock to trick the ethernet driver into thinking
the reference clock is at the correct frequency
* This masks the 'macb e000b000.ps7-ethernet eth0: unable to generate
target frequency: 125000000 Hz' message from the macb driver
