ASoC: SOF: Intel: hda: make DSPless mode work with DSP disabled in BIOS
When the DSP is disabled in the BIOS, the DSP_BAR and PP_BAR cannot be
accessed.
One possible objection noted in initial reviews is that this patch
adds a number of branches. However the number of branches is actually
limited in probe/suspend/resume routines mostly, so there isn't really
a degradation in terms of readability and maintainability. Adding yet
another level of abstraction/ops/callbacks would increase complexity
and not really help in terms of code reuse or readability and
maintainability. A split between controller and DSP driver would be
even more invasive.
