(1) The subject should be

  OvmfPkg/XenOvmf: use RealTimeClockRuntimeDxe from EmbeddedPkg

or similar.

(2) By tradition, ArmVirtPkg is welcome to consume modules from OvmfPkg,
but not the other way around. If you need

  ArmVirtPkg/Library/XenRealTimeClockLib

in an OvmfPkg platform, please move the library instance first to
OvmfPkg, redirecting the ArmVirtPkg references, and then consume the
library in OvmfPkg, internally to OvmfPkg.

Thanks
