The new PM support causes a warning when CONFIG_PM is disabled:
drivers/pci/host/pci-tegra.c:2482:12: error: 'tegra_pcie_pm_resume' defined but not used [-Werror=unused-function]
static int tegra_pcie_pm_resume(struct device *dev)
drivers/pci/host/pci-tegra.c:2463:12: error: 'tegra_pcie_pm_suspend' defined but not used [-Werror=unused-function]
static int tegra_pcie_pm_suspend(struct device *dev)
Marking the functions as __maybe_unused lets the compiler drop them
silently instead.
Fixes: b90b44154023 ("PCI: tegra: Add power management support")
