commit 0a65c6a9e204fdfa24fb4da0e84e38b9d269ba39
Author: Martin Roth <gaumless at gmail.com>

    add rtc_init() to romstage
    
    The FSP clears the bit that tells us whether or not the RTC has lost
    power when it sets up memory.  Because of this, we need to initialize
    the RTC in romstage instead of ramstage.
