Some drivers doesn't implement flash API page layout extension
which is causing the application crash once the API was calling.
This patch introduce system termination for this in those drivers
which doesn't implement extension. This will help to discover this
problem early.
It is not done by preprocessor check because it is possible to have
enabled a driver which support and a driver which doesn't support
this API simultaneously.
Now FLASH_PAGE_LAYOUT configuration option is accessible only in case
that at last one driver which implements mentioned API is enabled.

Add the STM32F0 Embedded Flash support in the flash_stm32 driver
interface.
The STM32F0 has a particularity or use the HSI as clock source
for the flash controller interface, so this clock must be
enabled directly in the case HSE or another clock is used by
the system clock.

L4 parts have a constant page size, so just rely on the HAL defines
that provide it, along with a read to the register which contains this
SoC's total size.

Add flash page layout support for STM32F4 SoCs.
This almost eliminates the need for flash_map.h, except for
STM32F4X_SECTOR_MASK, so delete the file and move the define into the
F4 implementation, to keep things simple.

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.
