This fixes for example 'xenpm get-cpufreq-para' with smt=off, which

This patch adds a couple of regs to the vm_event that are used by
the introspection. The base, limit and ar
bits are compressed into a uint64_t union so as not to enlarge the
vm_event.

Make sure the MSIX MMIO regions don't have p2m entries setup, so that
accesses to them trap into the hypervisor and can be handled by vpci.
This is a side-effect of commit 042678762 for PVH Dom0, which added
mappings for all the reserved regions into the Dom0 p2m.
