[PATCH 2/4]: QEMU interface for HVM virtual S3
  - add S3 suspend logic in PM1A control register. when guest write
    specific value to this register,
    QEMU will trigger S3 sleep by
    * reset all qemu device
    * set CMOS shutdown status as S3 resume, so that rombios will do S3
      resume later
    * call xc_domain_send_trigger to put HVM domain into S3 sleep
      state.
