    aarch64: Fix fp8 cpuinfo feature names
    
    The previous version of the patch was based on the mistaken assumption that
    features in /proc/cpuinfo had matching names to the feature names that gcc 
and
    gas accept.
    This patch enables the fp8 feature when the f8cvt feature is enabled, under 
the
    assumption that fpmr is always enabled when f8cvt is.
    
    Changelog:
    
    gcc/
            * config/aarch64/aarch64-option-extensions.def: (fp8): fix 
FEATURE_STRING.
            (fp8fma, ssve-fp8fma): Likewise.
            (fp8dot4, ssve-fp8dot4, fp8dot2, ssve-fp8dot2): Likewise.
