From: Roman Bolshakov <r.bolshakov@xxxxxxxxx>
It replaces hardcoded checks that select accelCPU/accelCPUModels
(formerly known as kvmCPU/kvmCPUModels) for KVM. It'll be cleaner to use
the function when multiple accelerators are supported in qemu driver.
Explicit KVM domain checks should be done only when a feature is
available only for KVM.
