Tegra: Support for scatterfile for the BL31 image
This patch provides support for using the scatterfile format as
the linker script with the 'armlink' linker for Tegra platforms.
In order to enable the scatterfile usage the following changes
have been made:
* provide mapping for ld.S symbols in bl_common.h
* include bl_common.h from all the affected files
* update the makefile rules to use the scatterfile and armlink
to compile BL31
* update pubsub.h to add sections to the scatterfile
NOTE: THIS CHANGE HAS BEEN VERIFIED WITH TEGRA PLATFORMS ONLY.
