virtio-vdpa: Support interrupt affinity spreading mechanism

Browse source

To support interrupt affinity spreading mechanism,
this makes use of group_cpus_evenly() to create
an irq callback affinity mask for each virtqueue
of vdpa device. Then we will unify set_vq_affinity
callback to pass the affinity to the vdpa device driver.
