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

From: Randy Dunlap
Date: Sat Apr 17 2021 - 02:57:02 EST

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.

ld: drivers/net/ethernet/xilinx/xilinx_emaclite.o: in function `xemaclite_of_probe':
xilinx_emaclite.c:(.text+0x9fc): undefined reference to `devm_ioremap_resource'

xilinx_axienet_main.c:(.text+0x942): undefined reference to `devm_ioremap_resource'

ld: drivers/net/ethernet/xilinx/ll_temac_main.o: in function `temac_probe':

ld: ll_temac_main.c:(.text+0x162e): undefined reference to `devm_platform_ioremap_resource'
