Allow guests to register secondary vcpu_time_info
Allow a guest to register a second location for the VCPU time info
structure for each vcpu. This is intended to allow the guest kernel
to map this information into a usermode accessible page, so that
usermode can efficiently calculate system time from the TSC without
having to make a syscall.
