Fabrice Gasnier 7dc0dddbe5 mfd: stm32-timers: Add support for stm32mp25 ...

Add support for STM32MP25 SoC. Use newly introduced compatible, to handle
new features.
Identification and hardware configuration registers allow to read the
timer version and capabilities (counter width, number of channels...).
So, rework the probe to avoid touching ARR register by simply read the
counter width when available. This may avoid messing with a possibly
running timer.
Also add useful bit fields to stm32-timers header file.
