Move translation tables into separate section
This patch moves the translation tables into their own section. This saves space that would otherwise have been lost in padding due to page table alignment constraints. The BL31 and BL32 bases have been consequently adjusted. Change-Id: Ibd65ae8a5ce4c4ea9a71a794c95bbff40dc63e65
