rtc: s5m: Add separate field for storing auto-cleared mask in register config
Some devices from S2M/S5M family use different register update masks for
different operations (alarm and register update). Now the driver uses
common register configuration and a lot of exceptions per device in code.
Before eliminating the exceptions and using specific register
configuration for given device, make the auto-cleared mask a separate
field. This is merely a refactoring.
