This patch solves the following warnings: arch/arm/mach-stm32mp/psci.c:
warning: no previous prototype for ‘psci_set_state’ [-Wmissing-prototypes] warning: no previous prototype for ‘psci_arch_cpu_entry’ [-Wmissing-prototypes] warning: no previous prototype for ‘psci_features’ [-Wmissing-prototypes] warning: no previous prototype for ‘psci_version’ [-Wmissing-prototypes] warning: no previous prototype for ‘psci_affinity_info’ [-Wmissing-prototypes] warning: no previous prototype for ‘psci_migrate_info_type’ [-Wmissing- prototypes] warning: no previous prototype for ‘psci_cpu_on’ [-Wmissing-prototypes] warning: no previous prototype for ‘psci_cpu_off’ [-Wmissing-prototypes] warning: no previous prototype for ‘psci_system_reset’ [-Wmissing-prototypes] warning: no previous prototype for ‘psci_system_off’ [-Wmissing-prototypes]

After rebase this patch cause compilation issue with sunci platform: it need to be updated
+arch/arm/cpu/armv7/sunxi/psci.c:279:15: error: conflicting types for 'psci_cpu_off'
