the st irqchip driver uses SIMPLE_DEV_PM_OPS to conditionally set its power management functions, but we get a warning about st_irq_syscfg_resume being unused when CONFIG_PM is not set:
drivers/irqchip/irq-st.c:183:12: error: 'st_irq_syscfg_resume' defined but not used [-Werror=unused-function] This adds a __maybe_unused annotation so the compiler knows it can silently drop it instead of warning.
