pinctrl: renesas: rzg2l: Make reverse order of enable() for disable()

[ Upstream commit dd462cf53e4dff0f4eba5e6650e31ceddec74c6f ]

We usually do reverse order of enable() for disable(). Currently, the
ordering of irq_chip_disable_parent() is not correct in
rzg2l_gpio_irq_disable(). Fix the incorrect order.
