For this reason, introduce a new PSCI DT helper function, psci_dt_pm_domains_parse_states(), which converts the hierarchically described domain idle states, into regular flattened cpuidle states. During the conversion, let's also insert the converted states into the cpuidle driver's array of idle states, as to enables the cpuidle framework to manage them.
