Add driver and device tree bindings support for Maxim max31329 real
time clock.

Changes since v2.
1. Removed log messages from error cases.
2. Removed OSF check from _read_alarm(), _set_alarm(), _set_time().
3. Removed CLKOUT pin initialization in probe() since it is configurable
   during runtime.
4. Configure wakeup support when interrupt is successfully configured
   or if the 'wakeup-source' parameter present in DT.
5. Added check for 'years' in _set_alarm so that it doesn't' cross current
   century.

Changes since v1.
1. Move 'allOf' after 'maintainers' in DT.
2. Add 'wakeup-source' into device tree bindings.
3. Add wakeup support depending on the 'wakeup-source' parameter from DT. 
4. Remove unused 'dev' member from device private data structure.
5. Use '__maybe_unused' attribute for of_device_id table.
6. Initialize local variable 'events' to 0 in interrupt handler.
