Subject: [PATCH] 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.
