ASoC: SOF: Add IPC4 private header

Add a struct sof_ipc4_fw_data to hold the firmware module data and
manifest FW header offset.
The FW reports data about the modules supported by the base FW in its
manifest and the FW header offset is platform dependent information.

This structure will be allocated when the ops are initialized for each
platform and populated when the FW is loaded.
