    mainboard/siemens/sitemp_g1p1: Fix CMOS checksum algorithm here, too
    
    Some time ago our CMOS checksum algorithm was changed under the topic:
        Fix our CMOS checksum algorithm so it matches what /dev/nvram expects
    
    Here is another copy of the algorithm that had to be updated.
