[Xen-devel] [PATCH v4 29/35] OvmfPkg/OvmfXen: Override PcdFSBClock to Xen vLAPIC timer frequency

[Anthony PERARD <anthony.perard@xxxxxxxxxx>]

PcdFSBClock is used by SecPeiDxeTimerLibCpu, the TimerLib
implementation. It will also be used by XenTimerDxe. Override
PcdFSBClock to match Xen vLAPIC timer frequency.
