ASoC: Intel: avs: ICCMAX recommendations for ICL+ platforms
For ICL+ platforms to avoid DMI/OPIO L1 entry during the base firmware
load procedure, HW recommends to set LTRP_GB to 95us and start an
additional CAPTURE stream in the background.
Once the load completes, original LTRP_GB value is restored and the
additional stream is released.
