Following migration of stm32f1xx series clock control driver to
STM32Cube LL API, cleanup stm32 code base in order to take into
account that this is the only clock driver available for stm32

Florian Vaussard 3540f03ef3 stm32f4: mpu: Add support for 1.5MB Flash / 320kB SRAM variants
The STM32F413ZH has 1536kB of Flash and 320kB of SRAM. This
configuration is currently not supported by ST MPU driver, so fill in
the blanks.

Note: The MPU does not support region size that is not a power-of-2 (see
the SIZE field in the MPU_RASR register). This is a problem for our
1536kB Flash region, so it was rounded up to the nearest choice. This is
possible because the memory in the range 0x0818000 - 0x0FFFFFFF is
"Reserved" and thus not mapped anyway.

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.

It is useless to include the pinmux for a peripheral if it is not

Florian Vaussard 4486ea0473 pinmux: stm32f4: Clean-up pinmux arrays
Clean-up the pinmux arrays as a preparatory work before adding more
pinmuxes.

This is achieved by the following two actions:
- Define the PAD macro to simplify the [x - 1] = y construct
- Reorder the declartions by bank / pin to make it easier to
  locate a pin among a high number of other pins, while minimizing the
  risk of conflict when two people add a new declaration for two
  different pins

This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t.  This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.

We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.

We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

Florian Vaussard 632a07d987 gpio: stm32: Use atomic set/reset in stm32_gpio_set()
The current implementation of stm32_gpio_set() uses the GPIO output data
register to change the state of individual GPIOs. The generated
assembler needs at least 3 instructions: load / modify / store.

This opens a small race window, for example if a thread and an
interrupt both try to change the state of the same GPIO bank.

Use the GPIO bit set/reset register to perform the atomic change without
locking.

This also has the benefit of a more optimised implementation, which can
be useful for GPIO-intensive work. Compare the new version:
