    AArch64: Remove special handling of generic cpu.
    
    In anticipation of adding new generic turning values this removes the hardcoding
    of the "generic" CPU and instead just specifies it as a normal CPU.
    
    No change in behavior is expected.
    
    gcc/ChangeLog:
    
            PR target/111370
            * config/aarch64/aarch64-cores.def: Add generic.
            * config/aarch64/aarch64-opts.h (enum aarch64_proc): Remove generic.
            * config/aarch64/aarch64-tune.md: Regenerate
            * config/aarch64/aarch64.cc (all_cores): Remove generic
            * config/aarch64/aarch64.h (enum target_cpus): Remove
            TARGET_CPU_generic.
