    RISC-V: Fix selection of pipeline model for sifive-7-series
    
    A few of the gcc.target/riscv/mcpu-*.c tests have been failing for a
    while now, due to the pipeline model for sifive-7-series not being
    selected despite -mtune=sifive-7-series.  The root cause is that the
    respective RISCV_TUNE entry points to generic instead.  Fix this.
    
    Fixes 97d1ed67fc6 ("RISC-V: Support --target-help for -mcpu/-mtune")
    
    gcc/ChangeLog:
    
            * config/riscv/riscv-cores.def (RISCV_TUNE): Update
            sifive-7-series to point to the sifive_7 pipeline description.
