Antonio Nino Diaz 468e238275 xlat v2: Remove architectural headers
They only contained one function that is easily integrated in the private
library header and the existing architectural C files.

This also helps making the library more portable, as the Makefile of the
library now doesn't use the variable INCLUDES, which is specific to this
codebase and doesn't respect the namespace of the library.

Antonio Nino Diaz 6a086061ad xlat v2: Make get/set attrs functions less verbose
It is useful to have LOG_LEVEL_VERBOSE because it prints the memory map
of each image, but that also means that the change_mem_attributes and
get_mem_attributes functions have verbose prints, and generate a too
long text output that hides other useful information.

As they were mostly there for debug purposes, this patch removes them.

Antonio Nino Diaz f9d58d1752 xlat v2: Clean debug xlat tables descriptor print
The previous debug output for EL1&0 translation regimes was too verbose,
which makes it hard to read and hides the intent behind the parameters
assigned to each region. This patch simplifies this output and makes the
outputs for EL3 and EL1&0 mostly the same. The difference is that in
EL1&0 it is specified whether the region is exclusively accessible from
EL1 (PRIV) or both EL0 and EL1 (USER).

For example:

    MEM-RW(PRIV)-NOACCESS(USER)-XN(PRIV)-XN(USER)-S
    MEM-RO(PRIV)-NOACCESS(USER)-EXEC(PRIV)-EXEC(USER)-S

After the change, it becomes this:

    MEM-RW-XN-PRIV-S
    MEM-RO-EXEC-PRIV-S

Antonio Nino Diaz fd2299e6b0 xlat v2: Split code into separate files
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).
