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

Include `plat_psci_common.c` from the new location The `plat_psci_common.c` was moved to the new location `plat/common` and a stub file was retained at previous location for compatibility. This patch modifies the platform makefiles to include the file from the new location. Change-Id: Iabddeeb824e9a5d72d176d7c644735966c8c0699

AArch32: Add essential ARM platform and FVP support This patch adds AArch32 support for FVP and implements common platform APIs like `plat_get_my_stack`, `plat_set_my_stack`, `plat_my_core_cos` for AArch32. Only Multi Processor(MP) implementations of these functions are considered in this patch. The ARM Standard platform layer helpers are implemented for AArch32 and the common makefiles are modified to cater for both AArch64 and AArch32 builds. Compatibility with the deprecated platform API is not supported for AArch32. Change-Id: Iad228400613eec91abf731b49e21a15bcf2833ea
