Merge series "soundwire/ASoC: abstract platform-dependent bases" from Bard Liao <yung-chuan.liao@linux.intel.com>:

shim base and alh base are platform-dependent. This series suggests
to use variables for those bases. It allows us to use different bases
for new platforms.

v2:
 - Update the commit message of "soundwire: move intel sdw register
   definitions to sdw_intel.h"

Bard Liao (6):
  soundwire: move intel sdw register definitions to sdw_intel.h
  ASoC: SOF: intel: add sdw_shim/alh_base to sof_intel_dsp_desc
  ASoC: SOF: intel: hda: remove HDA_DSP_REG_SNDW_WAKE_STS definition
  ASoC: SOF: intel: move sof_intel_dsp_desc() forward
  ASoC: SOF: intel: add snd_sof_dsp_check_sdw_irq ops
  soundwire: intel: introduce shim and alh base
