scsi: hisi_sas: Update all the registers after suspend and resume

After suspend and resume, the HW registers will be set back to their
initial value. We use init_reg_v3_hw() to set some registers, but some
registers are set via firmware in ACPI "_RST" method, so add reset handler
before init_reg_v3_hw().
