7a49356c77 power: Fix naming of Kconfig options controlling low power states
The SYS_POWER_LOW_POWER_STATE_SUPPORTED and SYS_POWER_LOW_POWER_STATE
suggests one low power state but these options control multiple
low power state. This commit uses plural in the names to indicate
that.

exti driver implementation does not fit all SoCs because
some EXTI ip does not match stm32_exti register map provided.
Instead of providing exti register map for all SoCs, use LL API
which abstracts IP variations and enable uniform use of the drivers

9612f9d840 soc: arm: st_stm32: Cleanup gpio function code.
All series STM32 have mostly the same GPIO architecture
and can share the same code for GPIO manipulation.
Functions of the external interrupt line control are also the same.
This patch extracts common code from them and put them into the 'common'
folder.

Functions of control GPIO of these series scattered in
soc/arm/st_stm32/stm32xx/ folders contain these functions:
stm32_gpio_flags_to_conf(), stm32_gpio_configure(), stm32_gpio_set(),
stm32_gpio_get, stm32_gpio_enable_int().
This patch merges them into the gpio_stm32.c file.

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
 - ALTERA_AVALON_SYSID
 - CLOCK_CONTROL_IMX_CCM
 - CPU_EM4_DMIPS
 - CPU_EM4_FPUDA
 - CPU_EM4_FPUS
 - FP_FPU_DA
 - I2C_GECKO

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

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

8eb734cd82 DT: Rename from dts.fixup to dts_fixup.h
The Zephyr configuration system uses many different files in many
different formats. It makes it a lot easier for users to understand
what these files do if when we use the correct file extensions.

To this end we rename the dts.fixup files to the correct file
extension '.h'.

This is a breaking change for out-of-tree fixup files. Such files will
be detected and given an appropriate error message.
