utils.h is included in various header files for the defines in it.
Some of the other header files only contain defines.  This allows the
header files to be shared between host and target builds for shared defines.

Recently types.h has been included in utils.h as well as some function
prototypes.

Because of the inclusion of types.h conflicts exist building host tools
abd these header files now.  To solve this problem,
move the defines to utils_def.h and have this included by utils.h and
change header files to only include utils_def.h and not pick up the new
types.h being introduced.

Remove utils_def.h from utils.h

This patch removes utils_def.h from utils.h as it is not required.
And also makes a minor change to ensure Juno platform compiles.

This patch modifies both versions of the translation table library
to use the mmap_attr_t type consistently wherever it is manipulating
MT_* attributes variables. It used to use mmap_attr_t or plain integer
types interchangeably, which compiles fine because an enumeration type
can be silently converted to an integer, but which is semantically
incorrect.

This patch removes this assumption by using the abstract type
'mmap_attr_t' all the time.

This patch adds an additional flag `XLAT_TABLE_NC` which marks the
translation tables as Non-cacheable for MMU accesses.

Added APIs to add and remove regions to the translation tables
dynamically while the MMU is enabled. Only static regions are allowed
to overlap other static ones (for backwards compatibility).

A new private attribute (MT_DYNAMIC / MT_STATIC) has been added to
flag each region as such.

The dynamic mapping functionality can be enabled or disabled when
compiling by setting the build option PLAT_XLAT_TABLES_DYNAMIC to 1
or 0. This can be done per-image.

TLB maintenance code during dynamic table mapping and unmapping has
also been added.

Fixes ARM-software/tf-issues#310

The folder lib/xlat_tables_v2 has been created to store a new version
of the translation tables library for further modifications in patches
to follow. At the moment it only contains a basic implementation that
supports static regions.

This library allows different translation tables to be modified by
using different 'contexts'. For now, the implementation defaults to
the translation tables used by the current image, but it is possible
to modify other tables than the ones in use.

Added a new API to print debug information for the current state of
the translation tables, rather than printing the information while
the tables are being created. This allows subsequent debug printing
of the xlat tables after they have been changed, which will be useful
when dynamic regions are implemented in a patch to follow.

The common definitions stored in `xlat_tables.h` header have been moved
to a new file common to both versions, `xlat_tables_defs.h`.

All headers related to the translation tables library have been moved to
a the subfolder `xlat_tables`.
