KVM: arm64: gic: Enable GICv3 CPUIF trapping on GICv5 hosts if required

Browse source

Factor out the enable (and printing of) the GICv3 CPUIF traps from the
main GICv3 probe into a separate function. Call said function from the
GICv5 probe for legacy support, ensuring that any required GICv3 CPUIF
traps on GICv5 hosts will be correctly handled, rather than injecting
an undef into the guest.
