    rs6000: Remove useless code related to -mno-power10
    
    Option -mpower10 was made as "WarnRemoved" since commit r11-2318,
    so -mno-power10 doesn't take effect any more.  This patch is to
    remove one line code which respects it.
    
    gcc/ChangeLog:
    
            * config/rs6000/rs6000.c (rs6000_disable_incompatible_switches): Remove
            useless related to option -mno-power10.
