Subject: [PATCH -next] ASoC: tegra186_asrc: mark runtime-pm functions as __maybe_unused

sound/soc/tegra/tegra186_asrc.c:90:12: error: ‘tegra186_asrc_runtime_resume’ defined but not used [-Werror=unused-function]
 static int tegra186_asrc_runtime_resume(struct device *dev)
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
sound/soc/tegra/tegra186_asrc.c:80:12: error: ‘tegra186_asrc_runtime_suspend’ defined but not used [-Werror=unused-function]
 static int tegra186_asrc_runtime_suspend(struct device *dev)
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Mark these functions as __maybe_unused to avoid this kind of warning.
