Define handlers specific to ACE platforms, that Frisco Lake (FCL), a PantherLake (PTL)-based platform, is founded upon. Most operations are still inherited from their predecessors with the major difference being AudioDSP cores management - replaced by DSP-domain power management. Software has to ensure the DSP domain is both powered on and its power-gating disabled before it can be utilized for streaming.
