ifdefs are hard, and in this driver the suspend/resume functions are
the only callers of some other helpers that trigger a harmless warning
when CONFIG_PM is disabled:
sound/soc/fsl/fsl_easrc.c:1807:12: warning: 'fsl_easrc_get_firmware' defined but not used [-Wunused-function]
1807 | static int fsl_easrc_get_firmware(struct fsl_asrc *easrc)
| ^~~~~~~~~~~~~~~~~~~~~~
sound/soc/fsl/fsl_easrc.c:303:12: warning: 'fsl_easrc_resampler_config' defined but not used [-Wunused-function]
303 | static int fsl_easrc_resampler_config(struct fsl_asrc *easrc)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
Remove the #ifdef and just mark the callers as __maybe_unused to
suppress the warnings altogether.
