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.
