rtc: s5m: add support for S2MPS14 RTC
Add support for S2MPS14 to the rtc-s5m driver. Differences in S2MPS14
(in comparison to S5M8767):
- Layout of registers
- Lack of century support for time and alarms (7 registers used for
storing time/alarm)
- Two buffer control registers: WUDR and RUDR
- No register for enabling writing time
- RTC interrupts are reported in main PMIC I2C device

If you say yes here you will get support for the
- RTC of Samsung S5M PMIC series.
+ RTC of Samsung S2MPS14 and S5M PMIC series.
This driver can also be built as a module. If so, the module
will be called rtc-s5m.
