Subject: [PATCH] ASoC: fsl_easrc: mark PM functions __maybe_unused
Git-commit: 087e3900a060cfc8516e02ea83fe6122da490d23
Patch-mainline: v5.8-rc1
References: jsc#SLE-16518

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.
