This patch introduces the 'pwr_domain_off_early' hook for
platforms wanting to perform housekeeping steps before the
PSCI framework starts the CPU power off sequence. Platforms
might also want to use ths opportunity to ensure that the
CPU off sequence can proceed.
The PSCI framework expects a return code of PSCI_E_DENIED,
if the platform wants to halt the CPU off sequence.

refactor(cpufeat): enable FEAT_DIT for FEAT_STATE_CHECKED
At the moment we only support FEAT_DIT to be either unconditionally
compiled in, or to be not supported at all.
Add support for runtime detection (ENABLE_DIT=2), by splitting
is_armv8_4_dit_present() into an ID register reading function and a
second function to report the support status. That function considers
both build time settings and runtime information (if needed).
We use ENABLE_DIT in two occassions in assembly code, where we just set
the DIT bit in the DIT system register.
Protect those two cases by reading the CPU ID register when ENABLE_DIT
is set to 2.
Change the FVP platform default to the now supported dynamic
option (=2), so the right decision can be made by the code at runtime.

feat: add support for poetry
New python dependencies are introduced by the memory mapping script.
Rather than add another `requirements.txt` utilise poetry. This is a
proper dependency management framework for Python. The two main upsides
of using poetry instead of the traditional requirements.txt are
maintainability and reproducibility.
Poetry provides a proper lock file for pinning dependencies, similar to
npm for JavaScript. This allows for separate environments (i.e. docs,
tools) to be created efficiently, and in a reproducible manner, wherever
the project is deployed. Having dependencies pinned in this manner is a
boon as a security focused project. An additional upside is that we will
receive security updates for dependencies via GitHub's Dependabot.

docs(porting): refer the reader back to the threat model
When porting TF-A to a new platform, it is essential to read the
threat model documents in conjunction with the porting guide to
understand the security responsibilities of each platform interface
to implement.
Add a note to highlight this in the porting guide.
docs(porting): move porting guide upper in table of contents
The porting guide is currently hosted under the 'Getting started'
section. Yet, porting the full firmware to a new platform is probably
not the first thing that one would do. Before delving into the
details, one would probably start by building the code for an emulated
platform, such as Arm FVP.
Furthermore, the porting guide is such a big and important document
that it probably deserves being visible in the main table of contents.
Thus, move it just above the list of supported platforms.
fix(intel): update boot scratch to indicate to Uboot is PSCI ON
There is a use case where kernel requested ATF to power off/on only CPU0.
However, after ATF power off/on CPU0, CPU0 did not back into the state
to wait for ATF. Instead, CPU0 continue to reentry SPL boot sequence
because CPU0 is master/primary core. This causing the system reboot from
SPL again, while the slave core still in kernel.
To resolve this, ATF is set the boot scratch register 8 bit 17 whenever
it is a request from kernel to power off/on only CPU0. So, if this boot
scratch bit is set, CPU 0 will be able to put into a state to wait for
ATF.
Qemu-tcg with GICv3 emulation enabled will by default configure MPIDR
topology to report up to 16 cpus per cluster. This is NOT overriden by
qemu's -smp setting, e.g. -smp 8,clusters=2,cores=4,threads=1 will still
generate MPIDR reads as if all 8 CPUs were within one cluster.
Increase the hardcoded limit to reflect that so that we accept PSCI
calls that provide MPIDRs based on what was actually read from the
emulated CPU.

This comes arguably from us somewhat abusing pointers to access MMIO
memory regions, which is not really covered by the C language.
Replace the pointer-dereferencing mmio_read_8() with an implementation
that uses inline assembly, to directly generate an 8-bit load
instruction. This avoids the compiler thinking that this access is using
a pointer it needs to jealously look after.
