serial: 8250: 8250_core: Fix irq name for 8250 serial IRQ
Using dev_name() as IRQ name during request_irq() might be misleading in case of serial over PCI. Therefore identify serial port IRQ using uart_port's name field. This will help mapping IRQs to appropriate ttySN(where N is the serial port index) instances.
