AArch64: Remove special handling of generic cpu.

Browse Source 
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.
