20544d66cc feat(stm32mp15-fdts): add SP_MIN versions of DT files
For ST STM32MP15 boards, where the default BL32 is OP-TEE, we add new
versions of DT files with -sp_min.dts extension to manage this
configuration. These files can be compiled directly, or, with the
previous patch, the same command line can be used and those sp_min
files will be automatically used, if AARCH32_SP=sp_min option is used.

33573ea684 fix(stm32mp1-fdts): re-enable RTC clock
On STM32MP15 ST boards, RTC clock configuration by OPTEE is not ready
yet. Re-enable it temporary to get LSE as clock source of RTC.

703a581e25 feat(stm32mp1-fdts): remove RTC clock configuration
RTC clock configuration is done now in OPTEE.
Note: The RTC clock source can only be configured once.
TF-A, configuring the RTC clock source will have no effect in OPTEE.

277d6af561 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.

2dc9fe70da fdts: stm32mp1: move FDCAN to PLL4_R
LTDC modifies the clock frequency to adapt it to the display. Such
frequency change is not detected by the FDCAN driver that instead
caches the value at probe and pretends to use it later.

This change fixes the issue by moving the FDCAN to PLL4_R,
leaving the LTDC alone on PLL4_Q.

Regulator configuration at boot takes more information from DT.
I2C configuration from DT is done in I2C driver.

else the platform does not boot.

Heavily modifies stm32_i2c.c since many functions move inside the source
file to remove redundant declarations.
