PSCI: Implement platform compatibility layer
The new PSCI topology framework and PSCI extended State framework introduces a breaking change in the platform port APIs. To ease the migration of the platform ports to the new porting interface, a compatibility layer is introduced which essentially defines the new platform API in terms of the old API. The old PSCI helpers to retrieve the power-state, its associated fields and the highest coordinated physical OFF affinity level of a core are also implemented for compatibility. This allows the existing platform ports to work with the new PSCI framework without significant rework. This layer will be enabled by default once the switch to the new PSCI framework is done and is controlled by the build flag ENABLE_PLAT_COMPAT. Change-Id: I4b17cac3a4f3375910a36dba6b03d8f1700d07e3
