e376b9417b drivers: watchdog: Convert drivers to new DT device macros
Convert watchdog drivers to use new DT variants of the DEVICE APIs.
    DEVICE_AND_API_INIT -> DEVICE_DT_DEFINE
    DEVICE_GET -> DEVICE_DT_GET
    DEVICE_DECLARE -> DEVICE_DT_INST_DECLARE

etc..

916dd0f6c4 drivers: watchdog: iwdg_stm32: Fix timeout calculation
CONFIG_IWDG_STM32_TIMEOUT allowed values of 100 us for initial watchdog
timeout, which was actually rounded to zero in the driver, which uses
milliseconds resolution for timeouts. This resulted in the reload value
being set to maximum possible (calculation: 0U - 1).

This commit updates the calculation of timeout minimum and maximum
values considering the actual LSI frequency of the used MCU.

As the resolution of CONFIG_IWDG_STM32_TIMEOUT in microseconds doesn't
make sense if the driver supports only milliseconds, it is renamed to
IWDG_STM32_INITIAL_TIMEOUT (this prevents accidental wrong settings in
existing firmware) and the unit is changed to ms.

824f423e54 misc: Replace assert include and calls by sys/__assert.h equivalent
Replace all calls to the assert macro that comes from libc by calls to
__ASSERT_NO_MSG(). This is usefull as the former might be different
depending on the libc used and the later can be customized to reduce
flash footprint.

e18fcbba5a device: Const-ify all device driver instance pointers
Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.

A coccinelle rule is used for this:

@r_const_dev_1
  disable optional_qualifier
@
@@
-struct device *
+const struct device *

@r_const_dev_2
 disable optional_qualifier
@
@@
-struct device * const
+const struct device *

Fixes #27399

With this patch, the specific flag IWDG_STM32_START_AT_BOOT
is replaced by the zephyr generic WDT_DISABLE_AT_BOOT.

This patches add a delay after setting the watchdog
to wait for the register (Prescaler and Counter registers)
to be updated before leaving (until LL_IWDG_IsReady is true)

a1aabbb08a drivers: watchdog: Pass timeout in ms if iwdg is started at boot
iwdg_stm32_install_timeout expects a timeout passed in
milli seconds. As the timeout is defined in micro
seconds in Kconfig.stm32, we need to divide by
USEC_PER_MSEC when CONFIG_IWDG_START_AT_BOOT is
activated because iwdg_stm32_install_timeout makes
the multiplication by USEC_PER_MSEC.

Fixes #18695

1b28cb0ff1 drivers/wdt: Rename STM32 IWDG files to follow naming rules
Basically, all driver file names should start with the driver type as
prefix: wdt_ in case of watchdogs here.

Maybe 'iwdg' keyword could be removed entirely, and also in function
names. However that is not the scope of this patch.
