After the conversion to devm_pinctrl_register, we get a warning in

struct sh_pfc *pfc = platform_get_drvdata(pdev);

This moves the variable definition inside of the same ifdef
that has the only user, to get a clean build again.



Similar patch from Geert also:
[PATCH] pinctrl: sh-pfc: Kill unused variable in sh_pfc_remove()

If devm_gpiochip_add_data() used then this may not be required.
