hw/net: cadence_gem: Add a new 'phy-addr' property

Browse source 
At present the PHY address of the PHY connected to GEM is hard-coded
to either 23 (BOARD_PHY_ADDRESS) or 0. This might not be the case for
all boards. Add a new 'phy-addr' property so that board can specify
the PHY address for each GEM instance.
