This patch defines deprecated platform APIs to enable Trusted Firmware components like Secure Payload and their dispatchers(SPD) to continue to build and run when platform compatibility is disabled. This decouples the migration of platform ports to the new platform API from SPD and enables them to be migrated independently. The deprecated platform APIs defined in this patch are : platform_get_core_pos(), platform_get_stack() and platform_set_stack(). The patch also deprecates MPIDR based context management helpers like cm_get_context_by_mpidr(), cm_set_context_by_mpidr() and cm_init_context(). A mechanism to deprecate APIs and identify callers of these APIs during build is introduced, which is controlled by the build flag WARN_DEPRECATED. If WARN_DEPRECATED is defined to 1, the users of the deprecated APIs will be flagged either as a link error for assembly files or compile time warning for C files during build.
