[PATCH v2 2/2] pinctrl: ocelot: Fix interrupt parsing

[Horatiu Vultur <horatiu.vultur@microchip.com>]

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
