Ruiyu Ni fe32096778 PcAtChipsetPkg/PcRtc: Fix a Y2K bug
The original driver cannot handle the case when system time runs from 1999/12/31 23:59:59
to 2000/1/1 0:0:0.
A simple test to set system time to 1999/12/31 23:59:59 can expose this bug.
The patch limits the driver to only support year in 100 range and decide the century value based
on the supporting range: Century either equals to PcdMinimalYear / 100 or equals to PcdMinimalYear / 100 + 1.

The patch passed the Y2K test.
However with year range [1998, 2097], when system time is 2097/12/31 23:59:59,
the next second system time will become 1998/1/1 0:0:0. I think it's a acceptable limitation.

rsun3 6bfa178cca Fixed 2 bugs in the RTC driver of PcAtChipsetPkg.
1. RtcTimeFieldsValid() has bug checking the validity of TIME fields, which causes SetTime() will not return EFI_INVALID_PARAMETER when it is fed with invliad time fields.
2. Logical error in handling Time Zone and Day Light Saving.GetTime() won't return Time Zone and Day Light Saving set by last SetTime() call.
