Patryk Duda 78ce5784eb drivers: flash: Add ex ops for STM32 option/control register block 
Introduce flash extended operations that can be used to disable access
to option and control registers until reset. Disabling access to these
registers improves system security, because flash content (or protection
settings) can't be changed even when exploit was found.

On STM32 devices, registers can be locked until reset by writing wrong
key during unlock procedure. It triggers a bus fault, so during the
procedure we need to ignore faults and clear bus fault pending bit.

Please note that option register disabling was implemented for devices
that have OPTCR register (F2, F4, F7 and H7). Implementation on other
devices requires more testing, since documentation is not precise
enough. Disabling control register was implemented for devices that
have CR register.
