[PATCH v4 06/23] scsi: hisi_sas: relocate get_ncq_tag_v2_hw()

From: John Garry
Date: Wed Jun 07 2017 - 10:54:48 EST


From: Xiang Chen <chenxiang66@xxxxxxxxxxxxx>

Relocate get_ncq_tag_v2_hw() to a common location, as
future hw versions will require it.
Also rename with "hisi_sas_" prefix for consistency.
