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.

If GPIO port for UART TX is less than 8, the register GPIO_AFRL should

or equal to 8. The macro GPIO_TX_ALT_SHIFT is removed and the GPIO port
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.

stm32mp1: use last page of SYSRAM as SCMI shared memory

SCMI shared memory is used to exchange message payloads between
secure SCMI services and non-secure SCMI agents. It is mapped
uncached (device) mainly to conform to existing support in
the Linux kernel. Note that executive messages are mostly short
(few 32bit words) hence not using cache will not penalize much
performances.

Platform stm32mp1 shall configure ETZPC to harden properly the
secure and non-secure areas of the SYSRAM address space, that before
CPU accesses the shared memory when mapped non-secure.

This change defines STM32MP_SEC_SYSRAM_BASE/STM32MP_SEC_SYSRAM_SIZE and
STM32MP_NS_SYSRAM_BASE/STM32MP_NS_SYSRAM_SIZE.

When NEON support is disabled, this is done for both BL2 and BL32 as
