[PATCH v8 17/35] pinctrl: airoha: add missed IRQ resource helpers

[Mikhail Kshevetskiy]

Without hooking .irq_request_resources, gpiolib cannot set
GPIOD_FLAG_USED_AS_IRQ. This breaks pin direction locking and can allow
userspace or another driver to reconfigure an active IRQ pin as an output

Fixes: 1c8ace2d0725 ("pinctrl: airoha: Add support for EN7581 SoC")
