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

浏览代码 
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.
