382e6fbccf drivers: watchdog: Make WDT_DISABLE_AT_BOOT default to y
This commit consolidates the meaning of WDT_DISABLE_AT_BOOT option as
"disabling watchdog at Zephyr system startup for the SoCs that enable
the watchdog by default after reset", and makes this default to y in
order to prevent unintentional processor reset by the watchdog when
not explicitly configured and fed by the application.

13b8b41676 drivers: watchdog: add system calls
wdt_install_timeout() was skipped as it installs an ISR-context
callback handler function. The rest are simple wrappers.

Added myself as the maintainer of the syscall handlers. WDT
subsystem appears to not currently have an owner.

Fixes: #21432

226d71a9c2 drivers: watchdog: Fix callback call on STM32 WWDG enable
When using the EWIF it is a good idea to clear it before enabling the
watchdog. Otherwise, the watchdog callback will be called upon watchdog
enable if EWIF is enabled. This patch fixes this case.

677f1e6db9 kconfig: Turn pointless/confusing 'menuconfig's into 'config's
Defining a symbol with 'menuconfig' just tells the menuconfig to display
any dependent symbols that immediately follow it in a separate menu.
'menuconfig' has no effect on symbol values.

Making a symbol that doesn't have any dependent symbols after it a
'menuconfig' should be avoided, because then you end up with an empty
menu, which is shown as e.g.

    [*] Enable foo ---

This is how it would be shown if there were children but they all
happened to be invisible as well.

With a regular 'config', it turns into

    [*] Enable foo

Change all pointless 'menuconfig's to 'config's.

See the section on 'menuconfig' on the Kconfig - Tips and Best Practices
page as well.

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.

e1639b5345 device: Extend device_set_power_state API to support async requests
The existing device_set_power_state() API works only in synchronous
mode and this is not desirable for devices(ex: Gyro) which take
longer time (few 100 mSec) to suspend/resume.

To support async mode, a new callback argument is added to the API.
The device drivers can asynchronously suspend/resume and call the
callback function upon completion of the async request.

This commit adds the missing callback parameter to all the drivers
to make it compliant with the new API.
