[PATCH 2/2] serial: 8250: 8250_core: Fix irq name for 8250 serial irq

[Vignesh R]

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