BL2_AT_EL3 is an overloaded macro which has two uses: 1. When BL2 is entry point into TF-A(no BL1) 2. When BL2 is running at EL3 exception level These two scenarios are not exactly same even though first implicitly means second to be true. To distinguish between these two use cases we introduce new macros. BL2_AT_EL3 is renamed to RESET_TO_BL2 to better convey both 1. and 2. Additional macro BL2_RUNS_AT_EL3 is added to cover all scenarious where BL2 runs at EL3 (including four world systems). BREAKING CHANGE: BL2_AT_EL3 renamed to RESET_TO_BL2 across the repository.
