When GPIO pin is requested as interrupt through `gpios` DT property the gpio_request() is called through the code path and when releasing GPIO pin it goes through the gpio_free() path, so drop calling gpio_request() in rzg2l_gpio_child_to_parent_hwirq() path and also drop rzg2l_gpio_free() in rzg2l_gpio_irq_domain_free(). This fixes case where rzg2l_gpio_free() was being called twice after the GPIO interrupt pin is freed (after unbinding the module). When GPIO pin is requested as interrupt through `interrupt` DT property this doesn't go through gpio_request()/gpio_free() code path.

This API allows pinctrl drivers to verify whether a pin is requested or not by checking if the pin is owned by either `gpio_owner` or `mux_owner`. GPIO pins used as interrupts through the `interrupts` DT property do not follow the usual `gpio_request`/`pin_request` path, unlike GPIO pins used as interrupts via the `gpios` property. As a result, such pins were reported as `UNCLAIMED` in the `pinmux-pins` sysfs file, even though they were in use as interrupts. With the newly introduced API, pinctrl drivers can check if a pin is already requested by the pinctrl core and ensure that pin is requested during when using as irq. This helps to ensure that the `pinmux-pins` sysfs file reflects the correct status of the pin.

The `rzg2l_gpio_irq_request_resources()` function now ensures that the pin is requested by the pinctrl core before locking the GPIO as an IRQ. This ensures that the `pinmux-pins` file in sysfs correctly reports the pin as claimed. Additionally, the `rzg2l_gpio_direction_input()` call is moved into the `rzg2l_gpio_irq_request_resources()` callback, as it makes sense to configure the GPIO pin as an input after it has been requested. The `rzg2l_gpio_irq_release_resources()` function unlocks the GPIO as an IRQ and then frees the GPIO, ensuring proper cleanup when the IRQ is no longer needed. This guarantees that the `pinmux-pins` file in sysfs correctly reports the pin as unclaimed. Also add a `pin_requested()` check in `rzg2l_gpio_free()` to return early if the pin is already released.
