Hypervisor detection is done very early on x86, and so can be used to also do some very early hypervisor related initialization. Such initialization is required when running as a Xen PVH guest, as for example the PIT needs to be replaced with an hypervisor based timecounter. Introduce an optional hook that gets called as part of the early hypervisor detection. No functional change intended.
