That's v1 or v2 in drivers/scsi/hisi_sas?
Seems like you need to implement the equivalent of the
pci_alloc_irq_vectors vector spreading for platform devices to get
your vectors properly assigned, and the have a blk_mq_of_map_queues
equivalent to blk_mq_pci_map_queues to map the queues based on the
interrupt assignment.
