4c8e8ea772 feat(st): update STM32MP DT files
This is an alignment with Linux DT files that have been merged in
stm32 tree [1], and will be in Linux 6.7.
The /omit-if-no-ref/ in overlay files are now removed, as already in
pinctrl files.

f351f9110f fix(stm32mp1-fdts): move /omit-if-no-ref/ to overlay files
To keep (as much as possible) alignment with Linux DT, move the
/omit-if-no-ref/ keywords to DT overlay files (fdts/stm32mp1*-bl*.dtsi).
This also ease checks for ST tools.

0aae96cfb9 feat(stm32mp1-fdts): use /omit-if-no-ref/ for pins nodes
With the /omit-if-no-ref/ keyword in DT, the non-referenced nodes
are just removed. This allows reducing the size of device tree blobs.
Setting it before pins node allows a size reduction of more than 2kB.
The corresponding nodes can also be removed from BL2 and BL32 DT
overlays.

51e223058f feat(stm32mp15-fdts): add Avenger96 board with STM32MP157A DHCOR SoM
This should replace the stm32mp157a-avenger96.dts with the new device
tree files split into the STM32MP15 DHCOR SoM definition and the
Avenger96 baseboard like it's done in Linux and U-Boot.

Differences to stm32mp157a-avenger96.dts:
- Enable sdmmc2 for booting from eMMC
- improved clock settings like in U-Boot commit b6055945
  "ARM: dts: stm32: Adjust PLL4 settings on AV96 again"
- improved DDR settings for DHSOMs like in U-Boot commit 92ca0f74
  "ARM: dts: stm32: Synchronize DDR setttings on DH SoMs"

TF-A with this new dts(i) files on this board was fully tested with
the latest OP-TEE developer setup.

0e480e0e8f fdts: stm32mp1: add alternative SDMMC2 pins to the pinctrl
The new pins—PA8, PA9, PE5, and PC7—are described in a new pinctrl node
named “sdmmc2-d47-3”, AKA phandle “sdmmc2_d47_pins_d”. These names are
identical to their Linux kernel counterparts (commit
7af08140979a6e7e12b78c93b8625c8d25b084e2).

214b4f9a46 fdts: stm32mp1: add I2C2 pins in the pinctrl
Some STM32MP1‐based boards, like Seeed Studio’s SoM‐STM32MP157C, have
the SoC connected to the PMIC via I2C2 instead of I2C4 (which is used on
the official ST development boards). This commit brings TF‑A one step
closer to boot on such boards.

The pins used, PH4 and PH5, are described in a new pinctrl node named
“i2c2-0”, AKA phandle “i2c2_pins_a”. These names are identical to their
Linux kernel counterparts (commit
7af08140979a6e7e12b78c93b8625c8d25b084e2).

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.
