This patch adds an argument to bl1_plat_post/pre_image_load() APIs to make it more future proof. The default implementation of these are moved to `plat_bl1_common.c` file. These APIs are now invoked appropriately in the FWU code path prior to or post image loading by BL1 and are not restricted to LOAD_IMAGE_V2. The patch also reorganizes some common platform files. The previous `plat_bl2_el3_common.c` and `platform_helpers_default.c` files are merged into a new `plat_bl_common.c` file. NOTE: The addition of an argument to the above mentioned platform APIs is not expected to have a great impact because these APIs were only recently added and are unlikely to be used.
