The remove callback is implemented as:

int mxs_pinctrl_remove(struct platform_device *pdev)
{
        struct mxs_pinctrl_data *d = platform_get_drvdata(pdev);

        pinctrl_unregister(d->pctl);
        iounmap(d->base);

        return 0;
}


So if I use devm_pinctrl_register() then the sequence will be different like
    iounmap()
    pinctrl_unregister()

And I did not want to change the sequence as dont know the side effect 
until I test it on actual platform which is not there with me.
