Fix checksum calculation both in romstage and ramstage.

The earlier fix for CMOS checksums only fixed the function rtc_set_checksum,
    which would fix the checksum, but then coreboot would no longer honor the
    settings because it assumed the checksum is wrong after this.
    This change fixes the remaining functions.
