+ This function checks to see if a controller can be managed by the ISA Bus
+ Driver. This is done by checking to see if the controller supports the
+ EFI_PCI_IO_PROTOCOL protocol, and then looking at the PCI Configuration
+ Header to see if the device is a PCI to ISA bridge. The class code of
+ PCI to ISA bridge: Base class 06h, Sub class 01h Interface 00h
+
+ Arguments:
+
+ This - The EFI_DRIVER_BINDING_PROTOCOL instance.
+ Controller - The handle of the device to check.
+ RemainingDevicePath - A pointer to the remaining portion of a device path.
+
+ Returns:
+
+ EFI_SUCCESS - The device is supported by this driver.
+ EFI_UNSUPPORTED - The device is not supported by this driver.
