ASoC: qcom: cleanup and fix dependency of QCOM_COMMON

SND_SOC_QCOM_COMMON depends on SOUNDWIRE for some symbols but this
is not explicitly specified using Kconfig depends. On the other hand
SND_SOC_QCOM_COMMON is also directly selected by the sound card
Kconfigs, this could result in various combinations and some symbols
ending up in modules and soundcard that uses those symbols as in-build
driver.

Fix these issues by explicitly specifying the dependencies of
SND_SOC_QCOM_COMMON and also use imply a to select SND_SOC_QCOM_COMMON
so that the symbol is selected based on its dependencies.

Also remove dummy stubs in common.c around CONFIG_SOUNDWIRE
