plat: marvell: Update SUBVERSION to match Marvell's forked version

Marvell's TF-A fork has SUBVERSION set to devel-18.12.2.

The only differences between Marvell's devel-18.12.0 and devel-18.12.2
versions are documentation updates and cherry-picked patches from TF-A
upstream repository.

So upstream TF-A has already all changes from Marvell's TF-A devel-18.12.2
fork and therefore update SUBVERSION to reflect this state.

plat: marvell: armada: Add new target mrvl_bootimage

This new target builds boot-image.bin binary as described in documentation.
This image does not contain WTMI image and therefore WTP repository is not
required for building.

Having ability to build just this boot-image.bin binary without full
flash-image.bin is useful for A3720 Turris MOX board which does not use
Marvell's WTP and a3700_utils.

To reduce duplicity between a8k and a3k code, define this new target and
also definitions for $(BUILD_PLAT)/$(BOOT_IMAGE) in common include file
marvell_common.mk.

For this purpose it is needed to include plat/marvell/marvell.mk file from
a3700_common.mk unconditionally (and not only when WTP is defined). Now
when common file plat/marvell/marvell.mk does not contain definition for
building $(DOIMAGETOOL), it is possible to move its inclusion at the top of
the a3700_common.mk file.

plat: marvell: armada: a3k: Add support for building $(DOIMAGETOOL)

Current binary wtptp/linux/tbb_linux which is specified in $(DOIMAGETOOL)
variable points to external pre-compiled Marvell x86_64 ELF linux binary
from A3700-utils-marvell WTP repository.

It means that currently it is not possible to compile TF-A for A3720 on
other host platform then linux x86_64.

Part of the A3700-utils-marvell WTP repository is also source code of
$(DOIMAGETOOL) TBB_Linux tool.

This change adds support for building $(DOIMAGETOOL) also for a3k platform.

After running $(MAKE) at appropriate subdirectory of A3700-utils-marvell
WTP repository, compiled TBB_linux tool will appear in WTP subdirectory
wtptp/src/TBB_Linux/release/. So update also $(DOIMAGETOOL) variable to
point to the correct location where TBB_linux was built.

To build TBB_linux it is required to compile external Crypto++ library
which is available at: https://github.com/weidai11/cryptopp.git

User needs to set CRYPTOPP_PATH option to specify path to that library.

After this change it is now possible to build whole firmware for A3720
platform without requirement to use pre-compiled/proprietary x86_64
executable binaries from Marvell.

zynqmp: pm: Filter errors related to clock gate permissions

Linux clock framework cannot properly deal with these errors. When the
error is related to the lack of permissions to control the clock we
filter the error and report the success to linux. Before recent changes
in clock framework across the stack, this was done in the PMU-FW as a
workaround. Since the PMU-FW now handles clocks and the permissions to
control them using general principles rather than workarounds, it can
no longer distinguish such exceptions and it has to return no-access
error.

Use constant stack size with RECLAIM_INIT_CODE

Currently, when RECLAIM_INIT_CODE is set, the
stacks are scaled to ensure that the entirety
of the init section can be reclaimed as stack.

This causes an issue in lib/psci/aarch64/psci_helpers.S,
where the stack size is used for cache operations in
psci_do_pwrdown_cache_maintenance(). If the stacks
are scaled, then the PSCI code may fail to invalidate
some of the stack memory before power down.

Resizing stacks is also not good for stability in general,
since code that works with a small number of cores may
overflow the stack when the number of cores is increased.

Change to make every stack be PLATFORM_STACK_SIZE big,
and allow the total stack to be smaller than the
init section.

Any pages of the init section not reclaimed as
stack will be set to read-only and execute-never,
for security.
