Fabien Dessenne a1d4ef1adf pinctrl: stm32: fix optional IRQ support to gpios 
To act as an interrupt controller, a gpio bank relies on the
"interrupt-parent" of the pin controller.
When this optional "interrupt-parent" misses, do not create any IRQ domain.

This fixes a "NULL pointer in stm32_gpio_domain_alloc()" kernel crash when
the interrupt-parent = <exti> property is not declared in the Device Tree.

Fixes: 0eb9f68333 ("pinctrl: Add IRQ support to STM32 gpios")
