[RFC v13 75/80] target/arm: move arm_cpu_finalize_features into cpu64


From: Claudio Fontana
Subject: [RFC v13 75/80] target/arm: move arm_cpu_finalize_features into cpu64
Date: Wed, 14 Apr 2021 13:26:45 +0200

all the features in arm_cpu_finalize_features are actually
TARGET_AARCH64-only now, since KVM is now only supported on 64bit.

Therefore move the function to cpu64.
