pata_imx: Use devm_ioremap_resource() to simplify code
Using devm_ioremap_resource() can lead to code simplication, as we don't need to explicitily check for error returned by platform_get_resource(). Also, no need to print an error message when devm_ioremap_resource() fails, as the OOM code code will shout loudly on such condition.
