Subject: [PATCH] net: xilinx: drivers need/depend on HAS_IOMEM

kernel test robot reports build errors in 3 Xilinx ethernet drivers. They all use ioremap functions that are only available when HAS_IOMEM is set/enabled. If it is not enabled, they all have build errors, so make these 3 drivers depend on HAS_IOMEM.
