(CAN_STM32).  Also have the STM32 CAN driver depend on being on a STM32

Erwan Gouriou 82403f68e2 drivers/flash: Move STM32F3 to generic STM32 series driver
A common driver is shared between stm32 chips, which was not the case
for stm32f3 series. As a consequence stm32f3 was not maintained
equally and was missing features such as flash layout or dts based
configuration.
Besides, drivers had some flows such as wrong bus clock and
missing HSI clock activation which lead to issues on boards not
using HSI as main clock.
As a consequence this commit moves stm32f3 series flash driver to
common stm32 flash drivers.

Fixes #4197

Ulf Magnusson 4638652214 Kconfig: Use 'default' instead of 'def_bool' in Kconfig.defconfig files
This can help find unused symbols. Those end up without a type if
'default' is used instead of 'def_bool', which generates a warning.

Search for "Kconfig.defconfig" in
https://docs.zephyrproject.org/latest/application/kconfig-tips.html for
a longer explanation.

Keep the 'def_bool' for the following symbols, which seem to be
deliberately defined only in Kconfig.defconfig files:

 - ALTERA_AVALON_I2C
 - ALTERA_AVALON_MSGDMA
 - ALTERA_AVALON_PIO
 - ALTERA_AVALON_QSPI

Andrzej Głąbek 20202902f2 dts_fixups: Use DT_ prefix in all defined labels not related to Kconfig
These changes were obtained by running a script  created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:

1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
   #define X Y)
3. Check if that name is also the name of a Kconfig option
   3.a If it is, then do nothing
   3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
       has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
   (.c, .h, .ld)

Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.

Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

Martin Bertsche 9892f40204 gpio: stm32 use dts extracted information to populate gpio instances.
The information extracted from the device tree is now used to initialize
GPIO device instances. Up until now the GPIO device driver made no use
of this information. Actual instance creation is still controlled using
the Kconfig method. Missing GPIO device tree nodes were added in the
process for STM32L073, STM32F413 and STM32F373.

The information for gpio instance initialization has already been
present for supported STM32 SoCs but remained unused. Changes in the
device tree had no effect on GPIO functionality and was essentially
redundant. Using the device tree for hardware description seems
plausible and less painful than a myriad of defines in some SoC
description header.

The change was implemented under the assumption that current device
trees provide a correct description of the SoCs. Base register addresses
and RCC register bits were not explicitly checked for each device.

Manual tests were executed on:
	- NUCLEO-F103RB
	- STM32F429I-DISCO
	- STM32F746G-DISCO
	- NUCLEO-F767ZI

Manual tests consisted of blinky on different GPIOs and pins on each
board.

sanitycheck was executed for all STM32 based boards
