irqchip/gic-v5: Check if impl is virt capable

Browse source

Now that there is support for creating a GICv5-based guest with KVM,
check that the hardware itself supports virtualisation, skipping the
setting of struct gic_kvm_info if not.

Note: If native GICv5 virt is not supported, then nor is
FEAT_GCIE_LEGACY, so we are able to skip altogether.
