pinctrl: renesas: rzn1: Enable missing PINMUX

[ Upstream commit f055ff23c331f28aa4ace4b72dc56f63b9a726c8 ]

Enable pin muxing (eg. programmable function), so that the RZ/N1 GPIO
pins will be configured as specified by the pinmux in the DTS.

This used to be enabled implicitly via CONFIG_GENERIC_PINMUX_FUNCTIONS,
however that was removed, since the RZ/N1 driver does not call any of
the generic pinmux functions.
