This path series adds the Merrifield IPC driver which is used to load and manage the DSP along with sending and receiving IPCs for PCM and compressed audio.
Changes in v3: * First patch is splitted into multiple patches * Now download fw during device resume * Removed runtime reference counting from driver context * Using dedicated functions instead ioctl * Addressed review comments
