  Routine Description:\r
  \r
    This function checks to see if a controller can be managed by the ISA Bus \r
    Driver. This is done by checking to see if the controller supports the \r
    EFI_PCI_IO_PROTOCOL protocol, and then looking at the PCI Configuration \r
    Header to see if the device is a PCI to ISA bridge. The class code of \r
    PCI to ISA bridge: Base class 06h, Sub class 01h Interface 00h \r

  Returns:\r
