usb: ohci-s3c2410: Use platform_get_irq() to get the interrupt

Accessing platform device resources directly has long been deprecated for DT as IRQ resources may not be available at device creation time. Drivers relying on the static IRQ resources is blocking removing the static setup from the DT core code.
