flash/nor/stm32xx: fix segfault accessing Cortex-M part number
Some of STM32 flash drivers read Cortex-M part number from
cortex_m->core_info.
In corner cases the core_info pointer was observed uninitialised
even if target_was_examined() returned true. See also [1]
Use the new and safe helper to get Cortex-M part number.
While on it switch also target_to_cm()/target_to_armv7m() to the safe
versions. This prevents a crash when the flash bank is misconfigured
with non-Cortex-M target.
Add missing checks for target_was_examined() to flash probes.
