This adds the TRNG Firmware Interface Service to the standard
service dispatcher. This includes a method for dispatching entropy
requests to platforms and includes an entropy pool implementation to
avoid dropping any entropy requested from the platform.

When building TF-A with USE_ROMLIB=1 and -j make options, the build fails with the following error:
make[1]: *** No rule to make target '/build/juno/debug/romlib/romlib.bin', needed by 'bl1_romlib.bin'.
This patch fixes that issue.

Default WTMI_IMG value was documented incorrectly. Also WTMI_IMG name may
be misleading as this option does not specify full WTMI image, just a main
loop (e.g. fuse.bin or custom RTOS image) without hardware initialization
code (DDR, CPU and clocks).

This change separates building of flash and UART images, so it is possible
to build only one of these images. Also this change allows make to build
them in parallel.

Target mrvl_flash now builds only flash image and mrvl_uart only UART
image. This change reflects it also in the documentation.

Currently a3700_common.mk makefile builds intermediate files in TF-A top
level directory and also outside of the TF-A tree. This change fixes this
issue and builds all intermediate files in $(BUILD_PLAT) directory.

Part of this change is also removal of 'rm' and 'mv' commands as there is
no need to remove or move intermediate files from outside of the TF-A build
tree.

This change introduces two new A3720 parameters, CRYPTOPP_LIBDIR and
CRYPTOPP_INCDIR, which can be used to specify directory paths to
pre-compiled Crypto++ library and header files.

When both new parameters are specified then the source code of Crypto++ via
CRYPTOPP_PATH parameter is not needed. And therefore it allows TF-A build
process to use system Crypto++ library.

For SoCs which do not implement RAS, use DSB as a barrier to
synchronize pending external aborts at the entry and exit of
exception handlers. This is needed to isolate the SErrors to
appropriate context.

However, this introduces an unintended side effect as discussed
in the https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/3440


A summary of the side effect and a quick workaround is provided as
part of this patch and summarized here:

The explicit DSB at the entry of various exception vectors in BL31
for handling exceptions from lower ELs can inadvertently trigger an
SError exception in EL3 due to pending asyncrhonouus aborts in lower
ELs. This will end up being handled by serror_sp_elx in EL3 which will
ultimately panic and die.

The way to workaround is to update a flag to indicate if the exception
truly came from EL3. This flag is allocated in the cpu_context
structure. This is not a bullet proof solution to the problem at hand
because we assume the instructions following "isb" that help to update
the flag (lines 100-102 & 139-141) execute without causing further
exceptions.
