Add documentation about plat_try_next_boot_source to bl1_platform_setup 

If boot redundancy is required in BL1 then the initialization
of the boot sequence must be done in bl1_platform_setup. In BL2,
we had to add a new function, bl2_preload_setup, because
bl2_platform_setup is called after the images are loaded, making it
invalid for the boot sequence initialization.

@ -1128,6 +1128,9 @@ This function executes with the MMU and data caches enabled. It is responsible
for performing any remaining platform-specific setup that can occur after the
MMU and data cache have been enabled.
if support for multiple boot sources is required, it initializes the boot
sequence used by plat\_try\_next\_boot\_source().
In ARM standard platforms, this function initializes the storage abstraction
layer used to load the next bootloader image.
