when CONFIG_PM is not defined, the compiler warns
CC drivers/dma/tegra210-adma.o
drivers/dma/tegra210-adma.c:635:12: warning: 'tegra_adma_runtime_suspend' defined but not used [-Wunused-function]
static int tegra_adma_runtime_suspend(struct device *dev)

drivers/dma/tegra210-adma.c:644:12: warning: 'tegra_adma_runtime_resume' defined but not used [-Wunused-function]
static int tegra_adma_runtime_resume(struct device *dev)
^
Although driver uses SET_RUNTIME_PM_OPS but doesn't add protection for these
symbols causing warning when CONFIG_PM is not defined, so add CONFIG_PM
around these symbols.
