Current implementation doesn't support change of div1 value if clk
has 2 divisor because div1 clk is the parent of the div2 clk and div2
clk does not have SET_RATE_PARENT flag.
This causes div1 value to be fixed and only value of div2 will be
adjusted according to required clock rate.
Example:
Consider a case of nand_ref clock which has 2 divisor and 1 mux.
The frequency of mux clock is 1500MHz and default value of div1 and
div2 is 15 and 1 respectively. So the final clock will be of 100MHz.
When driver requests 80MHz for nand_ref clock, clock framework will
adjust the div2 value to 1 (setting div2 value 2 results final clock
to 50MHz which is more inaccurate compare to 100Mhz) which results
final clock to 100MHz.
Ideally the value of div1 and div2 should be updated to 19 and 1
respectively so that final clock goes to around 78MHz.
This patch fixes above problem by allowing change in div1 value.

FORCE target is used as a dependency for other file targets which needs to
be always rebuilt. .PHONY target is standard Makefile target which specify
non-file targets and therefore needs to be always rebuilt.
Targets clean, realclean and distclean are .PHONY targets used to remove
built files. Correctly set that mrvl_clean target is prerequisite for these
clean targets to ensure that built files are removed.
Finally this change with usage of FORCE target allows to remove mrvl_clean
hack from the prerequisites of a8k ${DOIMAGETOOL} target which was used
just to ensure that ${DOIMAGETOOL} is always rebuilt via make subprocess.

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.

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.

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.

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.
