usb: dwc3: Switch to platform_get_irq_byname_optional()
The dwc3 code to get the "peripheral" / "host" / "otg" IRQ first tries platform_get_irq_byname() and then falls back to the IRQ at index 0 if the platform_get_irq_byname(). In this case we do not want platform_get_irq_byname() to print an error on failure, so switch to platform_get_irq_byname_optional() instead which does not print an error.
