In the next patch we add an extra step of setting the PSTATE
registers to a known state on el3 entry. In this patch we create
the function prepare_el3_entry to wrap the steps needed for before
el3 entry. For now this is only save_gp_pmcr_pauth_regs.

This patch adds the basic CPU library code to support the Poseidon CPU
in TF-A. Poseidon is derived from HunterELP core, an implementation of
v9.2 architecture. Currently, Hunter CPU the predecessor to HunterELP,
is supported in TF-A. Accordingly the Hunter CPU library code has been
as the base and adapted here.

This change removes reference counting support in clock gating
implementation for clocks that rely on non-secure only RCC resources.
As RCC registers are accessed straight by non-secure world for these
clocks, secure world cannot safely store the clock state and even
disabling such clock from secure world can jeopardize the non-secure
world clock management framework and drivers.
As a consequence, for such clocks, stm32_clock_enable() forces the clock
ON without any increment of a refcount and stm32_clock_disable() does
not disable the clock.

add a secure attribute to the clock: secure upon RCC[TZEN] (SEC),
secure upon RCC[TZEN] and RCC[MCKPROT] (MKP) or always accessible

At init, lookup clock tree to check if any of the secure clocks
is derived from PLL3 in which case PLL3 shall be secure.
Note that this change does not grow byte size of stm32mp1_clk_gate[].

With the FWU Multi Bank update feature, the platform can boot from one
of multiple banks(partitions). Pass the value of bank from which the
platform has booted as boot index to the Update Agent. The Update
Agent will match this boot index value against the active_index field
in the metadata, and update the metadata if there is a mismatch.
Fow now, the mechanism to pass the boot index is platform specific. On
the STM32MP1 platform, the boot index value is passed through a
memorey mapped TAMP register on the SoC.

The FWU multi bank feature supports multiple partitions or banks of
firmware components, where a platform can support having an active and
a backup partition(bank) of firmware images to boot from. This feature
identifies the images in a given bank using image GUID's --
this GUID value corresponds to the UniquePartitionGUID value used to
uniquely identify a GPT partition.
To support identification of images, add a member to the
partition_entry structure to store the UniquePartitionGUID value of
the GPT partition entry. This value is subsequently used to select the
firmware image to boot in a multi partition setup.

The Standard Version tool will not recognize a release header as a
release header without the minor version, and will overwrite them when
generating the next release changelog.
Additionally, it will not generate a link to the tag diff unless a tag
of the form `vX.Y.Z` exists. We ought to generate tags with this version
format in the future to ensure the diff links are generated.

With this change, we also move our commitlint configuration into a
new `changelog.yaml` file. This file holds the same data as `.cz.json`
previously did.
