ADU HWP updates for CI support, performance

  adjustments to support long running CI operations
    ignore autoinc mode for CI ttype
    include poll for data done prior to final status check

  ignore ADU operational/data hang reporting

  correctly report num_granules when running without autoinc

  performance enhancements:
    minimize SCOM operations for single shot transfers (15->9)
    reduce polling delays

  add simple test program to validate transfer sizes, measure perf
