cpuidle: psci: Add trace for PSCI domain idle
The trace event cpu_idle provides insufficient information for debugging
PSCI requests due to lacking access to determined PSCI domain idle
states. The cpu_idle usually only shows -1, 0, or 1 regardless how many
idle states the power domain has.
Add new trace events namely psci_domain_idle_enter and
psci_domain_idle_exit to trace enter and exit events with a determined
idle state.
These new trace events will help developers debug CPUidle issues on ARM
systems using PSCI by providing more detailed information about the
requested idle states.
