    miniport: fix broken support for revision 2
    
    RHBZ: 727886
    
    The io port range test was too large, requiring support for the
    new io ports introduced in revision 3. The purpose was just the opposite,
    to only require the revision 2 range, and use the revision 3 range only
    if the device claims revision 3.
    
    Fix by checking that either
     rev == 2 && io range contains 2
     rev > 2 && io range contains 3
