* config/aarch64/aarch64-cores.def (thunderxt88p1): Use thunderxt88
tunings.
(thunderxt88): Likewise.
* config/aarch64/aarch64.c (thunderxt88_prefetch_tune): New variable.
(thunderx_prefetch_tune): New variable.
(thunderx2t99_prefetch_tune): Update for the correct values.
(thunderxt88_tunings): New variable.
(thunderx_tunings): Use thunderx_prefetch_tune instead of
generic_prefetch_tune.
(thunderx2t99_tunings): Use AUTOPREFETCHER_WEAK.
