    nvptx.opt: Add sm_89 and sm_90a to -march-map=
    
    The -march-map= options maps the compute capability to the closest
    lower compute capability that has been implemented; for sm_89 and
    sm_90a, that were previously missing, that's currently -march=sm_80
    alias -misa=sm_80.
    
    gcc/ChangeLog:
    
            * config/nvptx/nvptx.opt (march-map=): Add sm_89 and sm_90a.
