 *  This routine installs an interrupt vector on CPU architectures
 *  using the Simple Vectored Interrupt Model.  This is the shared
 *  version which does nothing BSP specific.  A BSP specific version
 *  will be needed if you need to enable an interrupt source via
 *  some register.
 *
 *  INPUT PARAMETERS:
 *    handler - interrupt handler entry point
 *    vector  - vector number
 *    type    - 0 indicates raw hardware connect
 *              1 indicates RTEMS interrupt connect
 *
 *  OUTPUT PARAMETERS:  NONE
 *
 *  RETURNS:
 *    address of previous interrupt handler
