    powerpc/pseries: Fix vector5 in ibm architecture vector table
    
    With ibm,dynamic-memory-v2 and ibm,drc-info coming around the same
    time, byte22 in vector5 of ibm architecture vector table got set twice
    separately. The end result is that guest kernel isn't advertising
    support for ibm,dynamic-memory-v2.
    
    Fix this by removing the duplicate assignment of byte22.
    
    Fixes: 02ef6dd8109b ("powerpc: Enable support for ibm,drc-info devtree property")
