Subject: [PATCH] drivers: Let several drivers depends on HAS_IOMEM for 'devm_ioremap_resource'

Several drivers need 'devm_ioremap_resource' which need HAS_IOMEM enabled.
So let them depend on HAS_IOMEM.

The related error (with allmodconfig under score):

    MODPOST 1365 modules
  ERROR: "devm_ioremap_resource" [drivers/watchdog/tegra_wdt.ko] undefined!
  ERROR: "devm_ioremap_resource" [drivers/watchdog/of_xilinx_wdt.ko] undefined!
