If CONFIG_PM is not set, build warnings:

drivers/dma/tegra210-adma.c:747:12: warning: tegra_adma_runtime_resume defined but not used [-Wunused-function]
 static int tegra_adma_runtime_resume(struct device *dev)
drivers/dma/tegra210-adma.c:715:12: warning: tegra_adma_runtime_suspend defined but not used [-Wunused-function]
 static int tegra_adma_runtime_suspend(struct device *dev)

Mark the two function as __maybe_unused.
