Routine Description:

    This function is used to display debug information.

    Usage :
        HalR94aDebugPrint(
            (ULONG) 3,
            "1234",
            "Dbg : Current file is %s [%d]\n",
            __FILE__,
            __LINE__
            );

Arguments:

    DebugLevel - Debug level for output.
                 If DebugLevel less than R94aDebugLevel, not display.

    LedCharactor - Display charactor for LED.

    Message - Display format for console or debug-teminal.

Return Value:

    None.
