Calling disable_cache_as_ram() with valuables in stack is not
a stable solution, as per documentation AMD_DISABLE_STACK
should destroy stack in cache.
While we still preserve cache contents (there is wbinvd deep
inside AMD_DISABLE_STACK macro), we now actually do a stack
switch and much more closely meet the specification of CAR
teardown sequence in AGESA specifications.
We now somewhat incorrectly include files from agesa/ tree,
but the whole agesawrapper.c file removal will address the
issue of overall directory layout.

When allowing use of SSE instructions, stack must be
aligned to 16 bytes. Adjust x86 entry to C accordingly,
by pushing values to maintain the alignment.
For some builds, new toolchain and GCC-6.3 could emit
SSE instruction 'andps (%esp),%xmm0' with incorrectly
aligned esp, raising exception and thus preventing boot.

AMD_ENABLE_STACK was not called on x86_64 path for AGESA, while
it was for binaryPI.
Comments on BIST and cpu_init_detected were reversed, so fix those
too.

Replace with the more familiar AT&T syntax.
Tested by sha1sum(1)ing the object files, and checking the objdump that
the code in question was actually compiled.

It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.
This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

To backport features introduced with recent Chromebooks and/or Intel
boards in general, heavy work on the AMD AGESA platform infrastructure
is required. With the AGESA PI available in binary form only, community
members have little means to verify, debug and develop for the said
platforms.
Thus it makes sense to fork the existing agesawrapper interfaces, to give
AMD PI platforms a clean and independent sandbox. New directory layout
reflects the separation already taken place under 3rdparty/ and vendorcode/.
