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.
