 *  Description :
 *  -------------
 *
 *  Installs the IIC PIIX4 device driver services in 
 *  the IO system at the reserved device slot, found in the
 *  'sys_dev.h' file, which defines all major device numbers.
 *
 *  Note:
 *  This service is the only public declared interface function; all
 *  provided device driver services are static declared, but this
 *  function installs the function pointers in the io-system to
 *  enable the provided public driver services.
 *
 *  Parameters :
 *  ------------
 *
 *  None
 *
 *  Return values :
 *  ---------------
 *
 *  'OK'(=0)
 *  'ERROR_IO_ILLEGAL_MAJOR':  Illegal major device number
 *  'ERROR_IO_NO_SPACE':       Device slot already allocated
