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
