Changes for new version of image loading in BL1/BL2

This patch adds changes in BL1 & BL2 to use new version
of image loading to load the BL images.

Following are the changes in BL1:
  -Use new version of load_auth_image() to load BL2
  -Modified `bl1_init_bl2_mem_layout()` to remove using
   `reserve_mem()` and to calculate `bl2_mem_layout`.
   `bl2_mem_layout` calculation now assumes that BL1 RW
   data is at the top of the bl1_mem_layout, which is more
   restrictive than the previous BL1 behaviour.

Following are the changes in BL2:
  -The `bl2_main.c` is refactored and all the functions
   for loading BLxx images are now moved to `bl2_image_load.c`
   `bl2_main.c` now calls a top level `bl2_load_images()` to
   load all the images that are applicable in BL2.
  -Added new file `bl2_image_load_v2.c` that uses new version
   of image loading to load the BL images in BL2.

All the above changes are conditionally compiled using the
`LOAD_IMAGE_V2` flag.
