    hvm: add HVM_PARAM_VM_GENERATION_ID_ADDR
    
    HVM_PARAM_VM_GENERATION_ID_ADDR is the guest physical address of the
    VM Generation ID.  This parameter will be written by hvmloader and read
    by the toolstack when updating the gen. ID (e.g., after restoring from a
    snapshot).
    
    A HVM parameter is easier for the save/restore code to work with (than
    a XenStore key).
