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;

rtc: s5m: support different register layout

Prepare for adding support for S2MPS14 RTC device to the
rtc-s5m driver:

1. Add a map of registers used by the driver which differ between
   the chipsets (S5M876X and S2MPS14).

2. Move code of checking for alarm pending to separate function.

rtc: s5m: use shorter time of register update

Set the time needed for updating alarm and time registers to 0.45 ms.
The default is 7.32 ms which is too long and leads to warnings when
setting alarm or time:

rtc: s5m: remove undocumented time init on first boot

Remove the code for initializing time if this is first boot.

The code for detecting first boot uses undocumented field RTC_TCON in
RTC_UDR_CON register.  According to S5M8767's datasheet this field is
reserved.  On S2MPS14 it is not documented at all.  On device first boot
the registers will be initialized with reset value (2000-01-01 00:00:00).

The code might work on S5M8763 but still this does not look like a task
for RTC driver.

mfd/rtc: sec/s5m: rename SEC* symbols to S5M

Prepare for adding support for S2MPS14 RTC device to the rtc-s5m driver:

1. Rename SEC* symbols to S5M.
2. Add S5M prefix to some of defines which are different between S5M876X
   and S2MPS14.

This is only a rename-like patch, new code is not added.
