In the LunarLake hardware, the default IP ownership changed to the host driver, instead of the firmware in previous generation. In the absence of any capability negotiation, we need to assume a fixed partitioning between host driver and firmware. The OFLEN bit needs to be set as early as possible for resources handled by the firmware, since we can't control when the firmware might try to access the resources. For now DMIC and SSP are handled by the DSP firmware. SoundWire is a separate case, the OFLEN bit can be set when starting-up and resuming the aux device for each link.
