This patch removes RAS_FFH_SUPPORT macro which is the combination of ENABLE_FEAT_RAS and HANDLE_EA_EL3_FIRST_NS. Instead introduce an internal macro FFH_SUPPORT which gets enabled when platforms wants to enable lower EL EA handling at EL3. The internal macro FFH_SUPPORT will be automatically enabled if HANDLE_EA_EL3_FIRST_NS is enabled. FFH_SUPPORT along with ENABLE_FEAT_RAS will be used in source files to provide equivalent check which was provided by RAS_FFH_SUPPORT earlier. In generic code we needed a macro which could abstract both HANDLE_EA_EL3_FIRST_NS and RAS_FFH_SUPPORT macros that had limitations. Former was tied up with NS world only while the latter was tied to RAS feature. This is to allow Secure/Realm world to have their own FFH macros in future.
