[OE-core] [PATCH] qemuarm64: Add -machine gic-version=3 with kvm

qemuarm64 on aarch64 host errors out when using kvm

qemu-system-aarch64: PMU: KVM_SET_DEVICE_ATTR: Invalid argument
qemu-system-aarch64: failed to set irq for PMU
Aborted

machines with GICv3 that don’t support GICv2 guests you must have ‘-machine gic-version=3’ on the QEMU command line.
