mk/aosp_optee.mk: fix build dependency between a TA and its libraries

The LOCAL_REQUIRED_MODULES proposed by the commit [1] creates the
dependency for the specified modules and product to make sure they are
installed to the product image. But it doesn't create the dependency
between a TA and its libraries for build process to correctly link them.
Add the dependency back and change the depended file to the result file
in the intermediate directory instead of the installation directory.

arm64: Introduce permissive PAN implementation

Privileged Access Never (PAN) is a part of ARMv8.1 extension that
restricts accesses to unprivileged memory from privileged mode
in order to prevent unintended accesses to potentially malicious
memory.

This introduces configuration of PAN and helper functions
enter_user_access() and exit_user_access() that toggles PSTATE.PAN
that controls the behavior of PAN.

Current OP-TEE impelmentation is not ready to apply strict PAN policy
due to missing user-access function uses, etc.

Hence, this patch takes a very permissive approach (yet better
than nothing), where PAN is deactivated in the entire lifetime of
thread_svc_handler (i.e., system call).

ftrace: change implementation to use binary circular buffer

The current implementation of function tracing (CFG_FTRACE_SUPPORT)
produces human-readable text into the output buffer that is passed to
tee-supplicant and ultimately saved to the Linux filesystem. Two main
issues with that:

1. The string formatting code is somewhat complex. It introduces
significant overhead in the execution time of the instrumented
functions.
2. The various policies about how to handle a buffer full condition
(CFG_FTRACE_BUF_WHEN_FULL) are not very convenient. In particular,
"shift" is typically the most desirable option because it always
keeps the most recent entries, but it is very inefficient to the
point of not being usable in practice.

This commit addresses the above concerns by making the ftrace buffer
circular one, each entry being 64-bit value. The formatting code is
offloaded to a new Python script: scripts/ftrace_format.py. The
output is unchanged except for an added field showing the current
depth in the call stack.

Typical usage (captured on QEMUv8):

build$ mkdir -p ../tmp
build$ chmod a+w ../tmp
build$ make CFG_FTRACE_SUPPORT=y CFG_FTRACE_BUF_SIZE=15000 \
CFG_TA_MCOUNT=y CFG_ULIBS_MCOUNT=y CFG_SYSCALL_FTRACE=y \

To add link flags for a shared library, a makefile variable is used
that is called lib-ldflags$(libuuid). That's incorrect because the
UUID is not enough to uniquely identify a shared library in the build.
For example when both 32-bit and 64-bit user space is generated there
are two versions of the shared library with the same UUID. It is not
a problem at the moment because lib-ldflags$(libuuid) is used only
for one target: ta_arm64, but fix this anyways so that the variable
may be used for more complex cases.

Upgrading the TAs is basically a matter of replacing a few uint32_t
pointers with size_t pointers instead. This is done in as few places as
possible. So in particular the PKCS#11 TA might benefit from another
round of refactoring now that the contagious use of uint32_t as size
