KVM: arm64: Remove unused declarations

Browse Source 
Commit 53692908b0f5 ("KVM: arm/arm64: vgic: Fix source vcpu issues for GICv2 SGI")
removed vgic_v2_set_npie()/vgic_v3_set_npie() but not the declarations.
Commit 29eb5a3c57f7 ("KVM: arm64: Handle PtrAuth traps early") left behind
kvm_arm_vcpu_ptrauth_trap(), remove it.
Commit 2a0c343386ae ("KVM: arm64: Initialize trap registers for protected VMs")
declared but never implemented kvm_init_protected_traps() and
commit cf5d318865e2 ("arm/arm64: KVM: Turn off vcpus on PSCI shutdown/reboot")
declared but never implemented force_vm_exit().
