scsi: hisi_sas: Configure initial value of some registers according to HBA model

Browse source

For SAS HBAs of 920 and previous version, we use init_reg_v3_hw() to set
some registers which are related to HW boards. For SAS HBAs of 920B and
later version, those HW registers are set through firmware. And different
HBA models are distinguished through pci_dev->revision.
