[PATCH] ARM: dts: stm32: add U-Boot specific dtsi for stm32mp157f-dk2

[Dario Binacchi]

The STM32MP157F-DK2 board is a direct derivative of the STM32MP157C-DK2.
As explained by ST [1], the "STM32MP157F-DK2 is assembled with latest
STM32MP15 RevZ cut which is the only one available for new product now.
The major differences in this 'F' variant SoC are the increased max
frequency of the Cortex-A7 cores and the correction of some HW bugs
(Device Rev.Z, see errata ES0438)".

Introducing arch/arm/dts/stm32mp157f-dk2-u-boot.dtsi by including
stm32mp157c-dk2-u-boot.dtsi allows inheriting U-Boot specific properties
(e.g., bootph, fwumdata), avoiding code duplication and ensuring
feature parity.
