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: Generic probe compress operations Define system-agnostic probe compress flow which serves as a base for actual, hardware-dependent implementations. As per firmware spec, maximum of one extraction stream is allowed, while for injection, there can be plenty. Apart from probe_pointer, all probe compress operations are mandatory. Copy operation is defined as unified as its flow should be shared across all SOF systems.

ASoC: sof: use snd_compress_ops We can use snd_compress_ops. Let's switch to use it. Upstream code doesn't have sof_compressed_ops. This patch assume it is implemented at out-of-tree.
