flash: Rework and add flash device support for STM32L4x SoCs The STM32L4x SoCs embeds a slightly different embedded flash controller from the STM32F4x SoCs. This particular controller has the following properties : - Up to 2 512KiB banks divided in 2KiB pages - Flash can be accessed in any sizes - Flash must be written in 64bit aligned 64bit double-words The drivers/flash/flash_stm32f4x.c is refactored into a new common drivers/flash/flash_stm32.c and drivers/flash/flash_stm32l4x.c is created with the STM32L4x specific functions. To ease the refactoring and keep common functions, the STM32L4x flash headers are slightly modified to match the hardware reference naming and solve compilation issues.

Kconfig: Use a short, consistent style for prompts Consistently use config FOO bool/int/hex/string "Prompt text" instead of config FOO bool/int/hex/string prompt "Prompt text" (...and a bunch of other variations that e.g. swapped the order of the type and the 'prompt', or put other properties between them). The shorthand is fully equivalent to using 'prompt'. It saves lines and avoids tricking people into thinking there is some semantic difference. Most of the grunt work was done by a modified version of https://unix.stackexchange.com/questions/26284/ how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some of the rarer variations had to be converted manually.

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.
