fix(ti): align static device region addresses to reduce MMU table count

Align our device memory regions to the next highest MMU table level (LV2).
This allows the xlat_tables library code to use a single entry in the
higher order table, vs having to create a new table for LV3 entries.

This reduces our tables to just 4: 2 LV2 and 1 LV3 plus 1 spare in case
alignment changes ever cause one to be split. This saves 24KB of our
128KB total TF-A SRAM (~18%!).

While here, as USE_COHERENT_MEM does not change MAX_XLAT_TABLES but
does change our total MAX_MMAP_REGIONS, move that check accordingly.
