Without CONFIG_PM, some functions cause harmless warnings:
drivers/gpu/drm/tegra/sor.c:3984:12: error: 'tegra_sor_resume' defined but not used [-Werror=unused-function]
static int tegra_sor_resume(struct device *dev)
^~~~~~~~~~~~~~~~
drivers/gpu/drm/tegra/sor.c:3970:12: error: 'tegra_sor_suspend' defined but not used [-Werror=unused-function]
static int tegra_sor_suspend(struct device *dev)
^~~~~~~~~~~~~~~~~
Mark these as __maybe_unused so the compiler can drop them
silently.
