pinctrl: ocelot: Fix interrupt parsing

Browse Source 
In the blamed commit, it removes the duplicate of_node assignment in the
driver. But the driver uses this before calling into of_gpio_dev_init to
determine if it needs to assign an IRQ chip to the GPIO. The fixes
consists in using the platform_get_irq_optional
