ASoC: SOF: Add driver debug support.
Add debugFS files that can be used to expose DSP memories and and peripherals to userspace to assist with firmware debugging. Since we cannot rely on debugFS, errors are logged but don't stop execution. When a resource cannot be read in D3, it is optionally cached on suspend. Copying memories from IO will increase the suspend latency, this should only used in engineering builds w/ debug options. This part will have to be enhanced when support for D0ix states is provided, currently only D0 and D3 are supported.
