ASoC: Intel: avs: Firmware resources management utilities
With basefw runtime parameter handlers added, implement utility
functions to ease pipelines and modules allocation. IDA is enlisted to
help with that.
As firmware is modular and multiple binaries can be loaded on-demand
depending on the streaming scenario, custom firmware caching mechanism
is added.
