intel/skylake: ensure the RTC time is set

In 2014 or so the RTC code was changed to assume the ALTCENTRY
    register (0x32) as always being utilized for creating an rtc_time.
    However, one needs to ensure it's set at least once otherwise
    the year field in rtc_time is not sane.

In practice this doesn't matter unless somone wants to use the
    full year value. cmos_init() should do the same thing in the
    rtc fail case, but the machine I had never had that set correctly.

BUG=chrome-os-partner:47388
    BRANCH=None
    TEST=Booted glados w/ 0xff ALTCENTRY value. New value is 0x20.
