From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

The pinctrl-rzg2l driver uses APIs that are defined only if
CONFIG_IRQ_DOMAIN_HIERARCHY=y (irq_chip_*_parent() APIs). On the ARCH_RZG2L
CONFIG_IRQ_DOMAIN_HIERARCHY is selected anyway, e.g., by the
CONFIG_ARM_GIC_V3. Even so, make it explicit at the driver level for a
clearer view of the dependencies.

Thanks for your patch!

Compile-testing on m68k reveals that you also need

    select GPIOLIB_IRQCHIP

So I will add that when queuing in renesas-pinctrl for v6.9.
