    rtc: force mc146818 register D to a correct value
    
    On Panther Point PCH (and maybe cougar point), when some of the register
    D reserved bits are set, the RTC starts misbehaving (e.g. incrementing
    the year byte every second).
    There are probably undocumented features implemented behind those bits.
    Let's reset register D to a known state to ensure we get the expected
    RTC behavior.
