soundwire: qcom: use __maybe_unused for swrm_runtime_resume()

Browse Source 
swrm_runtime_resume() would not be defined when CONFIG_PM=n

This causes below build failure
drivers/soundwire/qcom.c:1460:12: error: 'swrm_runtime_resume' defined
but not used [-Werror=unused-function]

Mark the resume swrm_runtime_resume() with  __maybe_unused attribute.
