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.

- use __maybe_unused macro instead of wrapping in another ifdef.
