ASoC: rsnd: mark PM functions __maybe_unused
The suspend/resume callbacks are now optional, leading to a warning
when they are unused:
sound/soc/sh/rcar/core.c:1548:12: error: 'rsnd_resume' defined but not used [-Werror=unused-function]
static int rsnd_resume(struct device *dev)
^~~~~~~~~~~
sound/soc/sh/rcar/core.c:1539:12: error: 'rsnd_suspend' defined but not used [-Werror=unused-function]
static int rsnd_suspend(struct device *dev)
This marks the as __maybe_unused to avoid the warning.
Fixes: f8a9a29c4fe9 ("ASoC: rsnd: set pm_ops in hibernate-compatible way")
