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'.
Information about fwts (Firmware Test Suite) can be
found here:
https://wiki.ubuntu.com/Kernel/Reference/fwts

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