telemetry: Use DAI index as an instance ID

CPU ID is meant to be used as a measurement identifier only for IO
measurements related to IPC/IDC whereas for measuring DAIs IO, a DMA index
/DAI index shall be used instead. This commit contains this small
correction as well as cosmetic changes related to the DAI IO measurement.
