arm/arm64: KVM: vgic: Do not save GICH_HCR / ICH_HCR_EL2
The GIC Hypervisor Configuration Register is used to enable the delivery of virtual interupts to a guest, as well as to define in which conditions maintenance interrupts are delivered to the host. This register doesn't contain any information that we need to read back (the EOIcount is utterly useless for us). So let's save ourselves some cycles, and not save it before writing zero to it.
