feat(realm): added support to invoke RSI RDEV ABIs

- Updated DA RSI data types with RMM spec 1.1-alp11.1.
- Added support to call DA RSI RDEV ABIs like
  SMC_RSI_RDEV_CONTINUE
  SMC_RSI_RDEV_STOP
  SMC_RSI_RDEV_START
  SMC_RSI_RDEV_GET_INTERFACE_REPORT
  SMC_RSI_RDEV_LOCK
  SMC_RSI_RDEV_GET_INFO
  SMC_RSI_RDEV_GET_MEASUREMENTS
  SMC_RSI_RDEV_GET_STATE
  SMC_RSI_RDEV_GET_INSTANCE_ID
