[PATCH] KVM: arm/arm64: remove kvm_vgic_*early_init() functions

[Andre Przywara <andre.przywara@arm.com>]

kvm_vgic_early_init() and kvm_vgic_vcpu_early_init() were only used
with the old VGIC, on the new VGIC these functions do nothing.
Follow the comment in vgic-init.c and remove those functions and
their calls.
