Currently CONFIG_XILINX_AXI_EMAC=y implicitly depends on
CONFIG_HAS_IOMEM=y; consequently, on architectures without IOMEM we get
the following build error:

/usr/bin/ld: drivers/net/ethernet/xilinx/xilinx_axienet_main.o: in function `axienet_probe':
drivers/net/ethernet/xilinx/xilinx_axienet_main.c:1680: undefined reference to `devm_ioremap_resource'
/usr/bin/ld: drivers/net/ethernet/xilinx/xilinx_axienet_main.c:1779: undefined reference to `devm_ioremap_resource'
/usr/bin/ld: drivers/net/ethernet/xilinx/xilinx_axienet_main.c:1789: undefined reference to `devm_ioremap_resource'

Fix the build error by adding the unspecified dependency.
