ASoC: SOF/Intel: clarify SPDX license with GPL-2.0-only Remove the ambiguity with GPL-2.0 and use an explicit GPL-2.0-only tag.

ASoC: SOF: Add Sound Open Firmware driver core The Sound Open Firmware driver core is a generic architecture independent layer that allows SOF to be used on many different architectures and platforms. It abstracts DSP operations and IO methods so that the target DSP can be an internal memory mapped or external SPI or I2C based device. This abstraction also allows SOF to be run on many different VMs on the same physical HW. SOF also requires some data in ASoC PCM runtime data for looking up SOF data during ASoC PCM operations.

ASoC: SOF: support alternate list of machines For cases where an interface can be pin-muxed, we need to assess at probe time which configuration should be used. In cases such as SoundWire, we need to maintain an alternate list of machines and walk through them when the primary detection based on ACPI _HID fails.

ASoC: SOF: Introduce default_fw_filename member in sof_dev_desc Currently the FW filename is obtained from the ACPI matching table when determining which machine driver to use. In preparation for making the machine driver ACPI match optional for Device Tree platforms and moving the machine driver selection out of the SOF core, this patch introduces the default_fw_filename member in struct sof_dev_desc. Once the machine driver selection is moved out of SOF core, the nocodec_fw_filename will become obsolete and will be removed.

ASoC: SOF: nocodec: modify DAI link definitions The ignore_machine field in the component driver is used to ignore the FE DAI links defined in the machine driver, override BE fixups and set the stream names for the DAI links defined in the machine driver. This is required to make SOF compatible with the legacy machine drivers. In the case of the nocodec machine driver in SOF, there is no need to rely upon this ignore_machine logic in the core. Modify the machine driver to set DAI link stream names and the BE hw_params_fixup callback appropriately.
