KVM: arm/arm64: Demote kvm_arm_init_arch_resources() to just set up SVE 



The introduction of kvm_arm_init_arch_resources() looks like
premature factoring, since nothing else uses this hook yet and it
is not clear what will use it in the future.

For now, let's not pretend that this is a general thing:

This patch simply renames the function to kvm_arm_init_sve(),
retaining the arm stub version under the new name.
