This patch removes the plat_get_max_afflvl() platform API and instead replaces it with a platform macro PLATFORM_MAX_AFFLVL. This is done because the maximum affinity level for a platform is a static value and it is more efficient for it to be defined as a platform macro. NOTE: PLATFORM PORTS NEED TO BE UPDATED ON MERGE OF THIS COMMIT Fixes ARM-Software/tf-issues#265 Change-Id: I31d89b30c2ccda30d28271154d869060d50df7bf
