[PATCH] aarch64: Update FP8 dependencies for -mcpu=olympus

Tue, 22 Apr 2025 06:54:19 -0700 

Hi all,

We had not noticed that after g:299a8e2dc667e795991bc439d2cad5ea5bd379e2 the
FP8FMA and FP8DOT4 features aren't implied by FP8FMA. The intent is for
-mcpu=olympus to support all of them.
Fix the definition to include the relevant sub-features explicitly.

Bootstrapped and tested on aarch64-none-linux-gnu.

I’m pushing this to trunk, is it also ok for the GCC 15 branch? I’d like to 
have the right CPU features enabled for the realease.
Thanks,
Kyrill
