[Chen Gang]

They need HAS_IOMEM, so let them depend on it, the related error (with
allmodconfig under um):

    MODPOST 1205 modules
  ERROR: "syscall" [fs/hostfs/hostfs.ko] undefined!
  ERROR: "devm_ioremap_resource" [drivers/watchdog/tegra_wdt.ko] undefined!
  ERROR: "devm_ioremap_resource" [drivers/watchdog/of_xilinx_wdt.ko] undefined!
