ASoC: SOF: Add path definition for external firmware libraries
IPC4 based firmware supports dynamically loaded external libraries. The libraries will be not stored alongside of the firmware or tplg files. For intel platforms the default path will be: intel/avs-lib|sof-ipc4-lib/<platform>/ if a community key is used on the given machine then the libraries will be under 'community' directory, like it is done for the firmware itself.
