Sebastian Bøe b7eaeb9f0a cleanup: Use quote include instead of system include
When the header file is located in the same directory as the source
file it is better to use a relative quote-include, e.g.

than a system include like

Avoiding the use of system includes in these cases is beneficial
because;

* The source code will be easier to build because there will be fewer
system include paths.

* It is easier for a user to determine where a quote-include header
  file is located than where a system include is located.

* You are less likely to encounter aliasing issues if the list of
  system include paths is minimized.

Leandro Pereira 5e2303d54e drivers: flash: stm32f4x: `rc` should be declared as `int`
`rc` gets assigned values from function returning `int` and not
`u32_t`.

Fixes #4051.

Marti Bolivar 32482e9cb8 flash: stm32: stm32f4: add page layout support
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.

Marti Bolivar 4fea6dfe76 flash: stm32: clean up L4/F4 internal API
This is a prep work commit for adding flash page layout support.

The internal flash APIs for STM32 on L4 and F4 are a bit
inconsistent. Some routines take a pointer to the private data, others
don't. Those that do take it as a last argument instead of a
first. Additionally, some APIs are declared in flash_stm32.h that
aren't ever used by the family-specific files.

Clean this up by making everything take a struct device*, and marking
routines static in the common driver code when possible.

Michel Jaouen e9153979f0 flash: stm32: distinguish read/write for flash range valid
L4 write access requires 64 bits alignment
while L4 read access does not require any alignment.
To support specific check according to read/write,erase
a parameter is added to stm32_valid_range.

Neil Armstrong a9183cd518 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.

Neil Armstrong 7a8452c38b flash_stm32f4: bits were badly unset in erase and write functions
A typo was present ion the erase and write function were bit were
uncorrectly unset but all other bit except the mask were unset.
The code still worked because the two typos fixed themselves.

Neil Armstrong 6da68d214e flash_stm32f4: RDERR is not present on STM32F407
The RDERR bit is not present on F4x5 and F4x7 SoCs, so only use it when
available in the HAL.
