fb1d3bd933 feat(stm32mp15): disable OP-TEE shared memory
OP-TEE manages its own memory, and can open some areas through TZC400.
There is no need to configure this shared memory in TF-A.
Just assure that CFG_CORE_RESERVED_SHM=n for OP-TEE compilation.

42d4d3baac refactor(build): distinguish BL2 as TF-A entry point and BL2 running at EL3
BL2_AT_EL3 is an overloaded macro which has two uses:
	1. When BL2 is entry point into TF-A(no BL1)
	2. When BL2 is running at EL3 exception level
These two scenarios are not exactly same even though first implicitly
means second to be true. To distinguish between these two use cases we
introduce new macros.
BL2_AT_EL3 is renamed to RESET_TO_BL2 to better convey both 1. and 2.
Additional macro BL2_RUNS_AT_EL3 is added to cover all scenarious where
BL2 runs at EL3 (including four world systems).

BREAKING CHANGE: BL2_AT_EL3 renamed to RESET_TO_BL2 across the
repository.

(no behavior change). It will be set to 0 when OP-TEE is aligned, and
then later be removed.

9b2510b69d fix(security): apply SMCCC_ARCH_WORKAROUND_3 to A73/A75/A72/A57
This patch applies CVE-2022-23960 workarounds for Cortex-A75,
Cortex-A73, Cortex-A72 & Cortex-A57. This patch also implements
the new SMCCC_ARCH_WORKAROUND_3 and enables necessary discovery
hooks for Coxtex-A72, Cortex-A57, Cortex-A73 and Cortex-A75 to
enable discovery of this SMC via SMC_FEATURES. SMCCC_ARCH_WORKAROUND_3
is implemented for A57/A72 because some revisions are affected by both
CVE-2022-23960 and CVE-2017-5715 and this allows callers to replace
SMCCC_ARCH_WORKAROUND_1 calls with SMCCC_ARCH_WORKAROUND_3. For details

stm32mp_ddr_info contains general DDR information extracted from DT.
stm32mp_ddr_size moves to the generic side.
stm32mp1_ddr_priv contains platform private data.

stm32mp_ddr_dt_get_info() and stm32mp_ddr_dt_get_param() allow to
retrieve data from DT. They are located in new generic c/h files in
which stm32mp_ddr_param structure is declared. Platform makefile
is updated.

Adapt driver with this new classification.

88f4fb8fa7 feat(stm32mp1): allow configuration of DDR AXI ports number
A new flag STM32MP_DDR_DUAL_AXI_PORT is added, and enabled by default.
It will allow choosing single or dual AXI ports for DDR.

847c6bc8e6 feat(clk): add a minimal clock framework
This is mainly a clock interface with clk_ops callbacks.
Those callbacks are: enable, disable, get_rate, set_parent,
and is_enabled.
This framework is compiled for STM32MP1.

4dc77a35e3 refactor(stm32mp1): move stm32_save_boot_interface()
The function stm32_save_boot_interface()is moved to stm32mp1_private.c
file. The files stm32mp1_context.{c,h} are removed.
As return is always 0, change the function to return void.
Call it earlier, to be able to use it when configuring console.
