As the probe function matches against the "hisilicon,sas-controller-v1"
compatible string and contains mostly code that is specific to v1, I
think it would be cleaner to move that to the hisi_sas_v1_hw.c as well
and make the functions above static but make the common functions
called here (hisi_sas_init_add etc) global.

That would also include the hisi_sas_driver structure.
