ARM: dts: stm32: add stm32mp157f-dk2 board support

Browse source

STM32MP157F-DK2 board embeds a STM32MP157F SoC. This SoC contains the same
level of feature than a STM32MP157C SOC but A7 clock frequency can reach
800MHz, hence the inclusion of the newly introduced stm32mp15xf.dtsi.

As for other latest STM32 MPU families, STM32MP157F-DK2 relies on OP-TEE
SCMI services for SoC clock and reset controllers resources, and for PMIC,
now under OP-TEE control. That's why stm32mp157f-dk2-scmi.dtsi is
introduced, to move all clocks, resets and regulators to SCMI-based ones.

To "disable" SCMI, just need to comment stm32mp157f-dk2-scmi.dtsi inclusion
and to replace &scmi_v3v3 with &v3v3, then to disable arm_wdt and to enable
i2c4 and its subnodes for PMIC support by Linux. Reconfigure usbotg for
dual role with type-C support if needed.
