While thinking the variant patch I had posted, I went back to
look at the original cores which used the variant and saw there
was small cleanup for them since thunderx was no longer considered
a V8.1-a core but rather just a V8-a one; when I did that change
I didn't do the cleanups like is done in this patch set.
Note there is a core which uses the variant selection so we can't
remove the code there.

Since r7-6575-g71aba51d6460ff, thunderxt88 has been the same as thunderxt88p1 so let's make
them a true alias and remove the odd variant handling and moves it below thunderxt88.
Bootstrapped and tested on aarch64-linux-gnu with no regressions.
gcc/ChangeLog:
* config/aarch64/aarch64-cores.def (thunderxt88p1): Make an alias of thunderxt88 and
move below thunderxt88.
* config/aarch64/aarch64-tune.md: Regenerate.

Since these were already aliases just make it clear on that.
gcc/ChangeLog:
* config/aarch64/aarch64-cores.def: Add comment
saying thunderxt81/t83 are aliases of octeontx81/83.
