This patch mainly adds phy_port to HNS RoCE QP. This shall be
used in calculating the GSI QPN for the port.
Initally when RDMA is being established, all IB ports share a
QPN which later needs to be re-assigned to a particular GSI/QPN
and which is per-port.
This also fixes a bug in base driver where iboe port was being
used instead of phy_port at some places. This values might not
be same always.

This patch is meant to add support of ACPI to the Hisilicon RoCE
driver.

Changes done are primarily meant to detect the type and then either
use DT specific or ACPI spcific functions. Where ever possible,
this patch tries to make use of Unified Device Property Interface
APIs to support both DT and ACPI through single interface.

This patch depends upon HNS ethernet driver to Reset RoCE. This
function within HNS ethernet driver has also been enhanced to
support ACPI and is part of other accompanying patch with this
patch-set.
