Extend the max vcpu number for HVM guest.
- Originally the max vcpu number for HVM guest is 32, this patch
extend the number to 128 on x86_64 hypervisor. (For i386 hypervisor,
the max vcpu number is still 32).
- This patch extends the mp-table size to fit more vcpus.
- HVM PV driver should call VCPUOP_register_vcpu_info hypercall to
initialize the vcpu info if the vcpu number is more than 32.
