The translation library is useful elsewhere. Even though this repository
doesn't exercise the EL2 support of the library, it is better to have it
here as well to make it easier to maintain.
enable_mmu_secure() and enable_mmu_direct() have been deprecated. The
functions are still present, but they are behind ERROR_DEPRECATED and
they call the new functions enable_mmu_svc_mon() and
enable_mmu_direct_svc_mon().

Changed the names for consistency with the rest of the library. Introduced
new helpers that manipulate the active translation tables context.

This allows other parts of the code to reuse it. No functional changes.

The Exception Level is now detected at runtime. This means that it is not
needed to hardcode the EL used by each image.
This doesn't result in a substantial increase of the image size because
the initialization functions that aren't used are garbage-collected by
the linker.
In AArch32 the current EL has been changed from EL3 to EL1 because the
the AArch32 PL1&0 translation regime behaves more like the AArch64 EL1&0
translation regime than the EL3 one.

Instead of having one big file with all the code, it's better to have
a few smaller files that are more manageable:
- xlat_tables_core.c: Code related to the core functionality of the
library (map and unmap regions, initialize xlat context).
- xlat_tables_context.c: Instantiation of the active image context
as well as APIs to manipulate it.
- xlat_tables_utils.c: Helper code that isn't part of the core
functionality (change attributes, debug print messages).
