pinctrl: renesas: rzt2h: Restore correct pin mode on IRQ free
rzt2h_gpio_irq_domain_free() calls rzt2h_pinctrl_set_gpio_en() with
false leaving the pin in interrupt function instead of returning it to
GPIO mode.
Pass true to rzt2h_pinctrl_set_gpio_en() to take the pin out of
interrupt function after we're done using it as an IRQ.
rzt2h_pinctrl_set_pfc_mode() switches the pin to Hi-Z, losing the
previous PM value.
Save the PM value before switching to Hi-Z, and restore it after the
IRQ is freed.
