These two function share common code and only differ on how the affinity information is retrieved. Also, those functions are located in the block subsystem where it doesn't really fit in. They are virtio and pci subsystem specific. Introduce a new callback in struct bus_type to get the affinity mask. The callbacks can then be populated by the subsystem directly. All but one driver use the subsystem default affinity masks. hisi_sas v2 depends on a driver specific mapping, thus use the optional argument get_queue_affinity to retrieve the mapping.

This in preparation to retire blk_mq_pci_map_queues. For his_sas_v2_hw.c needs its own callback for retrieving the affinity. The generic bus_type get queue affinity callback is using pci_irq_get_affinity and not irq_data_get_affinity_mask. This allows it to replace the open code loop with blk_mq_hctx_map_queues at least.
