The RealTimeClockLib class header in edk2 mistakenly declares a function called LibRtcVirtualNotifyEvent(). No component ever calls this function crossing module boundaries; all RealTimeClockLib instances in edk2 and edk2-platforms are supposed to register (and do register) their SetVirtualAddressMap() notification functions.
In particular, DS3231RealTimeClockLib *itself* doesn't even use LibRtcVirtualNotifyEvent() -- the function is defined with an empty body, clearly in an understandable, but misguided, attempt, to conform to the (bogus) library interface. Remove the function. Build-tested only (with the Hisilicon platforms).
