Merge series "ASoC: Intel: Remove obsolete solutions and components" from Cezary Rojewski <cezary.rojewski@intel.com>:

Follow up to catpt series as mentioned in:
[PATCH v10 00/14] ASoC: Intel: Catpt - Lynx and Wildcat point
https://www.spinics.net/lists/alsa-devel/msg116440.html

As catpt is a direct replacement to sound/soc/intel/haswell, it leaves a
lot of code redudant. The second legacy solution - baytrail - is
deprecated for a long time by sound/soc/intel/atom with SOF flavor
available too.

This series addresses the redudancy and removes obsolete code. Along
with the legacy solutions, all orphaned components are removed too.

As a consequence, further cleanups are unlocked: sound/soc/intel/skylake
becomes the sole user of processing code found in
sound/soc/intel/common. Those are not part of this series.

Changes in v2:
- just a rebase so patch 04/13 applies cleanly
- left the tags as no actual changes done in between

Cezary Rojewski (13):
  ASoC: Intel: Remove haswell solution
  ASoC: Intel: Remove max98090 support for baytrail solution
  ASoC: Intel: Remove rt5640 support for baytrail solution
  ASoC: Intel: Remove baytrail solution
  ASoC: Intel: Remove SST ACPI component
  ASoC: Intel: Remove SST firmware components
  ASoC: Intel: Skylake: Unassign ram_read and read_write ops
  ASoC: Intel: Remove unused DSP operations
  ASoC: Intel: Remove unused DSP interface fields
  ASoC: Intel: Remove SST-legacy specific constants
  ASoC: Intel: Make atom components independent of sst-dsp
  ASoC: Intel: Remove sst_pdata structure
  ASoC: Intel: Remove sst_dsp_get_thread_context
