feat(cpu): add library support for Poseidon CPU

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.

feat(st-clock): do not refcount on non-secure clocks in bl32

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.

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.

feat(stm32mp1): add logic to select the images to be booted

With the FWU multi bank boot feature enabled, the platform can boot
from one of the multiple banks(partitions) containing the firmware
images. The bank whose firmware components are to be booted is read
from the FWU metadata structure -- the image to be booted is thus
derived by reading the metadata.

Read the metadata and set the image spec of the corresponding image
type to point to the partition from which the image is to be booted.
