      Issue Description
      TIOVX application fails due to UDMA TR event register failure.

      Root Cause
      UDMA shared resources sharing policy was incorrectly updated for c66x cores,
      due to which vision_apps was not able to get enough number of VINTR's they required
      on Main Navss.

      Resolution
      Allocating minimum resources to Mcu Navss, all the remaining resources(UDMA_RM_SHARED_RES_CNT_REST) to
      Main Navss fixes the issue.
