Don't return error information from console_flush ...

And from crash_console_flush.

We ignore the error information return by console_flush in _every_
place where we call it, and casting the return type to void does not
work around the MISRA violation that this causes. Instead, we collect
the error information from the driver (to avoid changing that API), and
don't return it to the caller.

stm32mp1: add macros to define PLAT_PARTITION_MAX_ENTRIES ...

There were fixed values when computing PLAT_PARTITION_MAX_ENTRIES.
Use STM32_BL33_PARTS_NUM and STM32_RUNTIME_PARTS_NUM. The first one is
for the number of copies of BL33. The second one depends on the use case
SP_min or OP-TEE. For OP-TEE, there are 3 partitions. For SP_min, as it
is in the same binary as BL2, it is set to 0. It will be set to 1 if
BL32 is in a separate binary.

fdts: stm32mp1: realign device tree with kernel ...

There is one dtsi file per SoC version:
- STM32MP151: common part for all version, Single Cortex-A7
- STM32MP153: Dual Cortex-A7
- STM32MP157: + GPU and DSI, but not needed for TF-A

The STM32MP15xC include a cryptography peripheral, add it in a dedicated
file.

There are 4 packages available, for which  the IOs number change. Have one
file for each package. The 2 packages AB and AD are added.

STM32157A-DK1 and STM32MP157C-DK2 share most of their features, a common
dkx file is then created.

Some reordering is done in other files, and realign with kernel DT files.

The DDR files are generated with our internal tool, no changes in the
registers values.

number is tested against GPIO_ALT_LOWER_LIMIT (=8) in

stm32mp1: SCMI clock and reset service in SP_MIN ...

This change implements platform services for stm32mp1 to expose clock
and reset controllers over SCMI clock and reset domain protocols
in sp_min firmware.

Requests execution use a fastcall SMC context using a SiP function ID.
The setup allows the create SCMI channels by assigning a specific
SiP SMC function ID for each channel/agent identifier defined. In this
change, stm32mp1 exposes a single channel and hence expects single
agent at a time.

The input payload in copied in secure memory before the message
in passed through the SCMI server drivers. BL32/sp_min is invoked
for a single SCMI message processing and always returns with a
synchronous response message passed back to the caller agent.

This change fixes and updates STM32_COMMON_SIP_NUM_CALLS that was
previously wrongly set 4 whereas only 1 SiP SMC function ID was to
be counted. STM32_COMMON_SIP_NUM_CALLS is now set to 3 since the
2 added SiP SMC function IDs for SCMI services.
