pinctrl: st: Convert to immutable irq_chip

Convert the driver to immutable irq-chip with a bit of
intuition.

I switched to using irqd_to_hwirq() consistently while we
are at it.

This driver does not use the GPIOCHIP_IRQ_RESOURCE_HELPERS
as it defines its own resource reservations, simply in
order to turn IRQ lines into inputs on initialization.

Also switched the open coded calls to gpiochip_lock_as_irq()
to gpiochip_reqres_irq() so we also get the right module
reference counting.
