[0/8] Add STM32MP25 LPTIM support: MFD, PWM, IIO, counter, clocksource

Message

This series adds support for STM32MP25 to MFD PWM, IIO, counter and
clocksource low-power timer (LPTIM) drivers.
This new variant is managed by using a new DT compatible string.
It comes with a slightly updated register set, some new features and new
interconnect signals inside the SoC.
Same feature list as on STM32MP1x is supported currently.
The device tree files add all instances in stm32mp251 dtsi file.
