PSCI: Migrate SPDs and TSP to the new platform and framework API

The new PSCI frameworks mandates that the platform APIs and the various
frameworks in Trusted Firmware migrate away from MPIDR based core
identification to one based on core index. Deprecated versions of the old
APIs are still present to provide compatibility but their implementations
are not optimal. This patch migrates the various SPDs exisiting within
Trusted Firmware tree and TSP to the new APIs.
