In STM32MP1 family, independant watchdogs (IWDG1 and IWDG2) are
dedicated to the MPU (Cortex-A7). Thus simply disable the feature
for STM32MP1 family.

The stm32mp1 family has no flash. The firmware is loaded directly in
RAM by stlink programmer or by Cortex-A7 bootloader/OS.
Thus bootloader is useless for this family, disable it.

Seems like the Interrupt flag for a Capture/Compare channel gets set when
- the CC-value is reached
- the timer resets before the CC value is reached.
We only want the first event and ignore the second one. Unfortunately I did
not find a way to disable the second event type, so it is filtered in software.
That is we need to
- ignore the CC-interrupts when the COUNT register register is reset
- ignore the CC-interrupts > TOP value/ARR (auto-reload register)
