[edk2] [Patch] PcAtChipSetPkg/PcRtc: Use PcdMinimalValidYear as the initial year value

[Ruiyu Ni]

RTC_INIT_YEAR was defined as 2001 so when PcdMinimalValidYear is 2002 the RtcTimeFieldsValid() returns failure
resulting the PcRtc driver not work.
The fix is to remove the RTC_INIT_YEAR definition and directly use PcdMinimalValidYear as the initial year value.
