Add library that parses the Kvmtool device tree and updates the dynamic PCDs describing the RTC Memory map. It also maps the MMIO region used by the RTC as runtime memory so that the RTC registers are accessible post ExitBootServices. Since UEFI takes ownership of the RTC hardware disable the RTC node in the DT to prevent the OS from attaching its device driver as well.
