drivers: counter: add Maxim DS3231 support The DS3231 is an I2C real-time clock with internal temperature compensated oscillator, maintaining civil time to 1 s precision with nominal 2 ppm accuracy from 0-40 Cel. The basic functionality is exposed as a counter that is always running at 1 Hz. Much more functionality is exposed as driver-specific API, including the ability to translate between the time scale of the DS3231 and the time scale of the Zephyr uptime clock. This allows correlation of events in the system clock to UTC, TAI, or whatever time scale is used to maintain the DS3231. Signed-off-by: Peter A. Bigot <pab@pabigot.com>

drivers: counter: Update drivers to use devicetree Kconfig symbol Update counter drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol to expose the driver and enable it by default based on devicetree. We remove 'depend on' Kconfig for symbols that would be implied by the devicetree node existing. Signed-off-by: Kumar Gala <galak@kernel.org>

lib: notify: build sys-notify conditionally. Add a new Kconfig and build this code conditionally, so we do not end up with this file being built for each zephyr app. Partial fix for #50654 Signed-off-by: Anas Nashif <anas.nashif@intel.com>
