SPM: Deprecate the current implementation

The current SPM is a prototype that only supports one secure partition
in EL0. The objective of SPM is to have multiple partitions. The current
MM interface isn't adequate for this, so it is needed to modify heavily
the code to add proper support for it.

However, there are platforms which are already using this (like SGI) and
removing the code would break it. For this reason, the current SPM code
has been duplicated in order to temporarily preserve compatibility. All
new improvements/changes to SPM will be done in the non-deprecated copy,
that may change without notice.

The new build option SPM_DEPRECATED has been introduced to select the SPM
implementation. It defaults to 1, that selects the deprecated SPM.

drivers/console: Reimplement MUTLI_CONSOLE_API framework in C

Now that we have switched to using the stack in MULTI_CONSOLE_API
framework functions and have factored all code involved in crash
reporting out into a separate file, there's really no reason to keep the
main framework code in assembly anymore. This patch rewrites it in C
which allows us to have a single implementation across aarch32/64 and
should be much easier to maintain going forward.

drivers/console: Link console framework code by default

This patch makes the build system link the console framework code by
default, like it already does with other common libraries (e.g. cache
helpers). This should not make a difference in practice since TF is
linked with --gc-sections, so the linker will garbage collect all
functions and data that are not referenced by any other code. Thus, if a
platform doesn't want to include console code for size reasons and
doesn't make any references to console functions, the code will not be
included in the final binary.

To avoid compatibility issues with older platform ports, only make this
change for the MULTI_CONSOLE_API.

Makefile: Support totally quiet output with -s

"-s" is a command line option to the make tool, to suppress normal output,
something to the effect of prepending every line with '@' in the Makefile.
However with our V={0|1} support, we now print the shortened command line
output in any case (even with V=1, in addition to the long line!).
Normally -s helps to not miss non-fatal warnings, which tend to scroll out
of the window easily.

Introduce a new Makefile variable ECHO, to control the shortened output.
We only set it in the (current default) V=0 case, and replace every
occurence of "@echo" with that variable.
When the user specifies "-s", we set ECHO to some magic string which
changes the output line into a comment, so the output is suppressed.

Beside suppressing every output for "-s", we also avoid the redundant
short output when compiling with V=1.

This changes the output to:
==========
$ make -s PLAT=.... bl31

Built build/.../release/bl31.bin

==========
$ make PLAT=.... bl31
...
CC lib/libc/strncmp.c
CC lib/libc/strnlen.c
...
==========
$ make V=1 PLAT=.... bl31
...
gcc -DDEBUG=0 .... -o build/.../release/libc/strncmp.o
gcc -DDEBUG=0 .... -o build/.../release/libc/strnlen.o
...

When attempting to compile TF-A with "SPD=something ARCH=aarch32", the

This is because the call to the error function is indented using a tab
whereas it's not part of a rule's recipe. Replace the tab by spaces.
