Subject: [PATCH v2 0/7] Introduce STM32MP157F-DK2 board

The main hardware difference with STM32MP157C-DK2 board is the SoC: 'F'
variant embeds a STM32MP157F SoC, which has the same level of features
than a STM32MP157C SoC but A7 clock frequency can reach 800Mhz (instead
of fixed 650Mhz for 'C' variant).
stm32mp157f-dk2 device tree reuses the existing sketeton for STM32MP15
DKx boards, but it is SCMI-based with I2C4 & PMIC managed by OP-TEE,
like other STM32 MPU boards (STM32MP135F-DK, STM32MP257F-DK/EV1, ...).
Himanshu's bindings patch [1] has been rerolled to introduce
st,stm32mp157f-dk2 compatible.

Changes in v2:
- Drop empty stm32mp15xa.dtsi and stm32mp15xd.dtsi files.
- Fulfill SCMI regulator defines and add Pascal's SoB
- Add patch [4/7] to use SCMI regulator defines
- Add patch [5/7] for OP-TEE async notif
- Link to v1: https://lore.kernel.org/r/20250527-stm32mp157f-dk2-v1-0-8aef885a4928@foss.st.com
