This patch implements ARM Standard Service as a runtime service and adds support for call count, UID and revision information SMCs. The existing PSCI implementation is subsumed by the Standard Service calls and all PSCI calls are therefore dispatched by the Standard Service to the PSCI handler. At present, PSCI is the only specification under Standard Service. Thus call count returns the number of PSCI calls implemented. As this is the initial implementation, a revision number of 0.1 is returned for call revision. Fixes ARM-software/tf-issues#62 Change-Id: I6d4273f72ad6502636efa0f872e288b191a64bc1
