PcAtChipsetPkg: Add PCD for RTC default year
Add PcdRtcDefaultYear to specify the default year to use when
the RTC is in an invalid state. Make sure PcdRtcDefaultYear is
>= PcdMinimalValidYear and <= PcdMaximalValidYear. Set the
default value for this PCD to PcdMinimalValidYear to preserve
the existing behavior. A platform DSC file can override this
default value setting.
