boards/zedboard: Fix Ethernet PHY dts node

* The Ethernet PHY on the ZedBoard is not guaranteed to be on address 7,
  instead use the phy broadcast address of 0 which is acceptable as no
  other devices are on the MDIO bus for the ZedBoard.

boards/qemumicroblaze: Added ramdisk boot args to device tree

The MicroBlaze kernel uses device tree boot args before it attempts to
use the arguments provided by the bootloader (e,g, u-boot/qemu).

This change expects that the qemumicroblaze machine is always loaded
with a initrd.
