    xen: remove PV suspend/resume support copyright
    
    Thew code for PV suspend/resume support has long been removed, also remove the
    copyright notice associated with it.
    
    There are still two copyright blocks with (to my understanding) slightly
    different wordings of the BSD 2 clause license.  I however don't feel like
    merging them due to those wording differences.
    
    The removal of the PV suspend/resume code was done in
    ed95805e90ec0f61683cd402a42e6f915339de7d.
