armv9a/tune: Add the support for the Neoverse N2 core
This adds the support for the Neoverse N2 core, even though the
Neoverse N2 core implements the Arm v9.0-A architecture, but the support
of it in GCC is based on the Arm v8.5-A architecture. Please see the
commit 50d9db203bc3 ("aarch64: Add support for Neoverse N2 CPU") in GCC
for more detail.
