On the ARM64 architecture, when CPUIDLE is not set in the configuration,
the compilation raises a couple of warnings:

drivers/firmware/psci.c:70:12: warning: 'psci_pd_power_off' defined but not used [-Wunused-function]
drivers/firmware/psci.c:273:12: warning: 'psci_set_suspend_mode_osi' defined but not used [-Wunused-function]

Fix those warnings by moving the functions inside the #ifdef CONFIG_CPU_IDLE
section.

Ha ha ! Sounds like my scripts are not yet ready :)

Sorry for the noise.
