watchdog: omap_wdt: Use devm_ioremap_resource()

Use devm_ioremap_resource() in order to make the code simpler,
and remove 'struct resource *mem' from 'struct omap_wdt_dev'
and omap_wdt_probe(), resplectively. because the 'mem' variables
are not used anymore. Also the redundant return value check of
platform_get_resource() is removed, because the value is checked
by devm_ioremap_resource().
