The private structure contain a pointer to phydev, but the structure
net_device already contain such pointer. So we can remove the pointer
phydev in the private structure, and update the driver to use the
one contained in struct net_device.

As device_node is only used by DT case, it is expected to find uniform
ways. So fwnode_handle is the suitable method.

This patch parse port-idx-in-ae in enet node. In NIC mode of DSAF, all 6
PHYs of service DSAF are taken as ethernet ports to the CPU. The
port-idx-in-ae can be 0 to 5. Here is the diagram:
            +-----+---------------+
            |            CPU      |
            +-+-+-+---+-+-+-+-+-+-+
              |    |   | | | | | |
           debug debug   service
           port  port     port
           (0)   (0)     (0-5)

In Switch mode of DSAF, all 6 PHYs of service DSAF are taken as physical
ports connect to a LAN Switch while the CPU side assume itself have one
single NIC connect to this switch. In this case, the port-idx-in-ae will
be 0 only.
            +-----+-----+------+------+
            |                CPU      |
            +-+-+-+-+-+-+-+-+-+-+-+-+-+
              |    |     service| port(0)

                          | | | | | |
                         external port

when port-idx-in-ae is not exists, old attribute port-id will be used
(only for compatible purpose, not recommended to use port-id in new code).

This patch replace the assoication between dsaf and enet from string
matching to object reference. It requires the DTS to be updated within
BIOS. Thanks god it can be done for all released boards.

This patchset adds support of Hisilicon Hip06 SoC to the existing HNS
ethernet driver.

The changes in the driver are mainly due to changes in the DMA
descriptor provided by the Hip06 ethernet hardware. These changes
need to co-exist with already present Hip05 DMA descriptor and its
operating functions. The decision to choose the correct type of DMA
descriptor is taken dynamically depending upon the version of the
hardware (i.e. V1/hip05 or V2/hip06, see already existing
hisilicon-hns-nic.txt binding file for detailed description). other
changes includes in SBM, DSAF and PPE modules as well. Changes
affecting the driver related to the newly added ethernet hardware
features in Hip06 would be added as separate patch over this and
subsequent patches.

This is to add basic ethernet support for HNS. It is one of the way to
use the HNS acceleration engine. But most of the decoding/encoding
capability of the AE cannot be used in this way.

This submit contains the basic feature as a ethernet driver. More will
be added later.
