[PATCH] ASoC: qcom: SND_SOC_SC7180 optionally depends on SOUNDWIRE

[Randy Dunlap]

If SOUNDWIRE is enabled, then SND_SOC_SC7180 should depend on
SOUNDWIRE to prevent SOUNDWIRE=m and SND_SOC_SC7180=y, which causes
build errors:

s390-linux-ld: sound/soc/qcom/common.o: in function `qcom_snd_sdw_prepare':
common.c:(.text+0x140): undefined reference to `sdw_disable_stream'
s390-linux-ld: common.c:(.text+0x14a): undefined reference to `sdw_deprepare_stream'
s390-linux-ld: common.c:(.text+0x158): undefined reference to `sdw_prepare_stream'
s390-linux-ld: common.c:(.text+0x16a): undefined reference to `sdw_enable_stream'
s390-linux-ld: common.c:(.text+0x17c): undefined reference to `sdw_deprepare_stream'
s390-linux-ld: sound/soc/qcom/common.o: in function `qcom_snd_sdw_hw_free':
common.c:(.text+0x344): undefined reference to `sdw_disable_stream'
s390-linux-ld: common.c:(.text+0x34e): undefined reference to `sdw_deprepare_stream'
