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.
