AMD/Persimmon: Add RTC init to CIMX SB800

Adding RTC init code to the Southbridge initialization
    code in 'late.c'.  This initializes the RTC so that the
    Date Alarm register is set to a valid value (0x00) at
    startup.  By setting the Date Alarm register to 0x00,
    it does not get evaluated along with the seconds,
    minutes, and hours when running fwts s3.

This was tested on a Persimmon but will apply to
    other mainboards as well.
