    [committed] [NFC] Fix riscv_init_cumulative_args for unused arguments
    
    The signature was still using ATTRIBUTE_UNUSED and actually marked one
    of the used arguments with ATTRIBUTE_UNUSED.
    
    This patch drops the decorations and instead remove the name of arguments
    which are actually unused which is the preferred way to handle this now
    when we can.
    
    Bootstrapped.  I didn't have test results on the platform where I
    bootstrapped, so no results to compare against.  Given its NFC, I
    think we're OK without the regression results.
    
    gcc/
            * config/riscv/riscv.cc (riscv_init_cumulative_args): Update and
            fix bugs in signature.
