PM: tracing: Hide psci_domain_idle events under ARM_PSCI_CPUIDLE

The events psci_domain_idle_enter and psci_domain_idle_exit events are
only called when CONFIG_ARM_PSCI_CPUIDLE is defined. As each event can
take up to 5K (less for DEFINE_EVENT()) regardless if they are used or
not, it's best not to define them when they are not used. Add #ifdef
around these events when they are not used.
