hw/arm: xlnx: Set all boards' GEM 'phy-addr' property value to 23 

When cadence_gem model was created for Xilinx boards, the PHY address
was hard-coded to 23 in the GEM model. Now that we have introduced a
property we can use that to tell GEM model what our PHY address is.
Change all boards' GEM 'phy-addr' property value to 23, and set the
PHY address default value to 0 in the GEM model.
