Anthony PERARD July 4, 2019, 2:42 p.m. UTC 
A Xen PVH guest doesn't have a RTC that OVMF would expect, so
PcatRealTimeClockRuntimeDxe fails to initialize and prevent the
firmware from finish to boot. To prevent that, we will use
XenRealTimeClockLib which simply always return the same time.
This will work on both Xen PVH and HVM guests.
