rtc: add support for Abracon AB-RTCMC-32.768kHz-B5ZE-S3 I2C RTC chip

This patch adds support for Abracon AB-RTCMC-32.768kHz-B5ZE-S3
RTC/Calendar module w/ I2C interface.

This support includes RTC time reading and setting, Alarm (1 minute
accuracy) reading and setting, and battery low detection.  The device also
supports frequency adjustment and two timers but those features are
currently not implemented in this driver.  Due to alarm accuracy
limitation (and current lack of timer support in the driver), UIE mode is
not supported.

If you say yes here you get support for the Abracon
AB-RTCMC-32.768kHz-B5ZE-S3 I2C RTC chip.
