soundwire: intel: fix intel_suspend/resume defined but not used warning

Browse source 
When CONFIG_PM_SLEEP is not defined, GCC throws compilation warnings:

drivers/soundwire/intel.c:1799:12: warning: ‘intel_resume’ defined but not
used [-Wunused-function]
 static int intel_resume(struct device *dev)
            ^~~~~~~~~~~~
drivers/soundwire/intel.c:1683:12: warning: ‘intel_suspend’ defined but not
used [-Wunused-function]
 static int intel_suspend(struct device *dev)
            ^~~~~~~~~~~~~

Fix by using __maybe_unused macro.
