Ideally, you dont need the call of sh_pfc_unregister_gpiochip() if you 
use the devm_gpiochip_add_data() which is already available on all 
subsystem.

int sh_pfc_unregister_gpiochip(struct sh_pfc *pfc)
{
         gpiochip_remove(&pfc->gpio->gpio_chip);
#ifdef CONFIG_SUPERH
         gpiochip_remove(&pfc->func->gpio_chip);
#endif
         return 0;
}

So you can get rid of this calls and lines.
