Create BL stage specific translation tables
This patch uses the IMAGE_BL<x> constants to create translation tables specific
to a boot loader stage. This allows each stage to create mappings only for areas
in the memory map that it needs.
Fixes ARM-software/tf-issues#209
Change-Id: Ie4861407ddf9317f0fb890fc7575eaa88d0de51c
