ArmVirtPkg: Add Kvmtool RTC Fdt Client Library 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.

ArmVirtPkg: Fix depex in kvmtool guest Rtc library The Rtc library for the kvmtool guest firmware configures the RTC controller address range as runtime memory by calling the gDS->SetMemorySpaceAttributes(). The SetMemorySpaceAttributes() function has a dependency on the CPU Arch Protocol. If the CPU Arch Protocol is not installed the call to set the memory attributes fails with error code EFI_NOT_AVAILABLE_YET. Therefore, set the library dependency on the CPU Arch protocol.
