pinctrl: starfive: jh7110: Fix failure to set irq after CONFIG_PM is enabled
The issue was found when we enabled CONFIG_PM and tested edge events using
libgpiod.
> # gpiomon -r gpiochip0 55
> gpiomon: error waiting for events: Permission denied
`gpiomon` will call irq_chip_pm_get() and then call pm_runtime_resume_and_get()
if (IS_ENABLED(CONFIG_PM) && sfp->gc.irq.domain->pm_dev).
pm_runtime_resume_and_get() will fail if the runtime pm of pinctrl device
is disabled.
As we expect the pinctrl driver can be always working and never suspend
during runtime, unset sfp->gc.irq.domain->pm_dev to make sure
pm_runtime_resume_and_get() won't be called when setting irq.
