Subject: [PATCH -next] memory: tegra: mark PM functions as __maybe_unuse

Without this, we get a couple of warnings when CONFIG_PM
is disabled:

drivers/memory/tegra/tegra186.c:1578:12: warning: 'tegra186_mc_resume' defined but not used [-Wunused-function]
 static int tegra186_mc_resume(struct device *dev)
            ^~~~~~~~~~~~~~~~~~
drivers/memory/tegra/tegra186.c:1573:12: warning: 'tegra186_mc_suspend' defined but not used [-Wunused-function]
 static int tegra186_mc_suspend(struct device *dev)
            ^~~~~~~~~~~~~~~~~~~

Fixes: 177602b00641 ("memory: tegra: Add system sleep support")
