Subject: [PATCH 06/19] scsi: hisi_sas: us start_phy in PHY_FUNC_LINK_RESET

From: Xiang Chen <chenxiang66@...ilicon.com>

When a PHY_FUNC_LINK_RESET is issued, we need to fill the
transport identify_frame to SAS controller before the
PHYs are enabled.

Without this, we may find that if a PHY which belonged to
a wideport before the reset may generate a new port id.
