[libvirt] [PATCH v3 1/2] qemu: Restrict usage of hpet and kvm.pit timers by unsupported architectures

hpet and kvm.pit clock timers are specific to x86 architecture and are not suppose to be used in other architectures. This patch restricts the usage of hpet and kvm.pit timers in unsupported architectures.
