Current code mandates loading of SCP_BL2/SCP_BL2U images for all CSS platforms. On future ARM CSS platforms, the Application Processor (AP) might not need to load these images. So, these items can be removed from the FIP on those platforms. BL2 tries to load SCP_BL2/SCP_BL2U images if their base addresses are defined causing boot error if the images are not found in FIP. This change adds a make flag `CSS_LOAD_SCP_IMAGES` which if set to `1` does: 1. Adds SCP_BL2, SCP_BL2U images to FIP. 2. Defines the base addresses of these images so that AP loads them. And vice-versa if it is set to `0`. The default value is set to `1`. Change-Id: I5abfe22d5dc1e9d80d7809acefc87b42a462204a
