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.
