Two more header files missing extern "C" construct

[Robert S. Grimes]

Hi,

I found two more files that are missing the C++ extern "C" construct:

    #ifdef __cplusplus
    extern "C" {
    #endif

    <definitions>

    #ifdef __cplusplus
    }
    #endif

The affected files are in /cpukit/include/rtems:

    bspIo.h
    pci.h

Thanks,
-Bob
