[ Upstream commit 47edc0104c61d609b0898a302267b7269d87a6af ]
Commit 5bd773242f75 ("soundwire: qcom: avoid dependency on CONFIG_SLIMBUS") removed hard dependency on Slimbus for qcom driver but it results in build failure when: CONFIG_SOUNDWIRE_QCOM=y CONFIG_SLIMBUS=m
drivers/soundwire/qcom.o: In function `qcom_swrm_probe': qcom.c:(.text+0xf44): undefined reference to `slimbus_bus'
Fix this by using IS_REACHABLE() in driver which is recommended to be used with imply.
