    uart/pci: support 16550A PCI serial devices
    
    Expand the current check to also attach the ns8250 driver to devices
    reporting as 16550A.  This has been tested to work on a real device.
    
    From an inspection of the code in the ns8250 driver it seems like it should
    support up to 16950A devices, but I don't have hardware to ensure that,
    hence be conservative with the change.
