net: zynq_gem: Dont run any phy detection logic for GMII case

This patch bypasses phy detection logic for GMII interface
and just depend on phy address received from DT. This patch
is required as phy detection logic is different for some phys
like xilinx phy which can be connected over SGMII and GMII
interface.
This fixes the issue of ethernet failures when xilinx phy is
connected over GMII interface.
