Yatharth Kochar 170fb93dec Add optional PSCI STAT residency & count functions ... This patch adds following optional PSCI STAT functions: - PSCI_STAT_RESIDENCY: This call returns the amount of time spent in power_state in microseconds, by the node represented by the `target_cpu` and the highest level of `power_state`. - PSCI_STAT_COUNT: This call returns the number of times a `power_state` has been used by the node represented by the `target_cpu` and the highest power level of `power_state`. These APIs provides residency statistics for power states that has been used by the platform. They are implemented according to v1.0 of the PSCI specification. By default this optional feature is disabled in the PSCI implementation. To enable it, set the boolean flag `ENABLE_PSCI_STAT` to 1. This also sets `ENABLE_PMF` to 1.
