Yin Fegnwei 08139c34f7 hv: add vmx_off and update exec_vmxon_instr

To handle cpu down/up dynamically, arcn needs to support vmx off/on
dynamically. Following changes is introduced:
  vmx_off will be used when down AP. It does:
    - vmclear the mapped vcpu
    - off vmx.

  exec_vmxon_instr is updated to handle start and up AP both. It does
    - if vmx was on on AP, load the vmxon_region saved. Otherwise,
      allocate vmxon_region.
    - if there is mapped vcpu, vmptrld mapped vcpu.
