Subject: [PATCH v2 00/11] Rework and fix STM32MP15x PHYTEC dts

This patch series rename and reorganize the STM32MP15x PHYTEC
baseboard (phyBOARD-Sargas) and SoM (phyCORE-STM32MP15x) device tree
files.
Indeed, the current device tree naming and organization is not really
consistent as it does not align with others STM32MP boards (use common
dtsi file as much as possible, use one dtsi for SoM and one dtsi for
baseboard).

The series also fixes some important pinctrl issues and minor one (coding
style). Additional pinctrl is also added for the optionnal interfaces
that are not enabled by default (FMC, LTDC, DCMI, PWM).

Changes in v2:
- Rebase on v6.16-rc5
- Rework Patch 3 (stm32.yaml): for board description, keep "compatible"
string identifiers as before to not break ABI. But use "enum" type
instead of "const" for the SoM and phyBOARD indentifiers.
