Older Qualcomm platforms like APQ8016 do not have hardware support for SoundWire, so kernel configurations made specifically for those platforms will usually not have CONFIG_SOUNDWIRE enabled. Unfortunately commit8d89cf6ff2("ASoC: qcom: cleanup and fix dependency of QCOM_COMMON") breaks those kernel configurations, because SOUNDWIRE is now a required dependency for SND_SOC_QCOM_COMMON (and in turn also SND_SOC_APQ8016_SBC). Trying to migrate such a kernel config silently disables SND_SOC_APQ8016_SBC and breaks audio functionality. The soundwire helpers in common.c are only used by two of the Qualcomm audio machine drivers, so building and requiring CONFIG_SOUNDWIRE for all platforms is unnecessary. There is no need to stuff all common code into a single module. Fix the issue by moving the soundwire helpers to a separate SND_SOC_QCOM_SDW module/option that is selected only by the machine drivers that make use of them. This also allows reverting the imply/depends changes from the previous fix because both SM8250 and SC8280XP already depend on SOUNDWIRE, so the soundwire helpers will be only built if SOUNDWIRE is really enabled.
