Instead of hardcoding a level 1 table as the base translation level table, let the code decide which level is the most appropriate given the virtual address space size. As the table granularity is 4 KB, this allows the code to select level 0, 1 or 2 as base level for AArch64. This way, instead of limiting the virtual address space width to 39-31 bits, widths of 48-25 bit can be used. For AArch32, this change allows the code to select level 1 or 2 as the base translation level table and use virtual address space width of 32-25 bits. Also removed some unused definitions related to translation tables. Fixes ARM-software/tf-issues#362 Change-Id: Ie3bb5d6d1a4730a26700b09827c79f37ca3cdb65
