feat(common/debug): add new macro ERROR_NL() to print just a newline

Existing macro ERROR() prints string "ERROR" followed by string
specified by caller. Therefore via this existing macro it is not
possible to end incomplete / existing line by a newline character.

This change adds a new macro ERROR_NL() which prints just a newline
character without any prefix. Implementation of this macro is done via a
new function tf_log_newline() which based on supplied log level either
return or print newline character.

If needed in future based on this tf_log_newline() function can be
defined also macros for other log levels.

Remove references to old project name from common files

The project has been renamed from "Arm Trusted Firmware (ATF)" to
"Trusted Firmware-A (TF-A)" long ago. A few references to the old
project name that still remained in various places have now been
removed.

This change doesn't affect any platform files. Any "ATF" references
inside platform files, still remain.

Merge pull request #1726 from antonio-nino-diaz-arm/an/includes

Sanitise includes across codebase

Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a282 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca33988b9 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

Allow setting log level back to compile time value

When using the tf_log_set_max_level() function, one can dynamically
set the log level to a value smaller than then compile time specified
one, but not equal. This means that when the log level have been
lowered, it can't be reset to the previous value. This commit modifies
this function to allow setting the log level back to the compile time
value.

Implement log framework

This patch gives users control over logging messages printed from the C
code using the LOG macros defined in debug.h Users now have the ability
to reduce the log_level at run time using the tf_log_set_max_level()
function. The default prefix string can be defined by platform by
overriding the `plat_log_get_prefix()` platform API which is also
introduced in this patch.

The new log framework results in saving of some RO data. For example,
when BL1 is built for FVP with LOG_LEVEL=LOG_LEVEL_VERBOSE, resulted
in saving 384 bytes of RO data and increase of 8 bytes of RW data. The
framework also adds about 108 bytes of code to the release build of FVP.
