This patch adds common changes to support AArch32 state in BL1 and BL2. Following are the changes: * Added functions for disabling MMU from Secure state. * Added AArch32 specific SMC function. * Added semihosting support. * Added reporting of unhandled exceptions. * Added uniprocessor stack support. * Added `el3_entrypoint_common` macro that can be shared by BL1 and BL32 (SP_MIN) BL stages. The `el3_entrypoint_common` is similar to the AArch64 counterpart with the main difference in the assembly instructions and the registers that are relevant to AArch32 execution state. * Enabled `LOAD_IMAGE_V2` flag in Makefile for `ARCH=aarch32` and added check to make sure that platform has not overridden to disable it.

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
