Issue:
- Network stuck if autonegotion fails
Issue root cause:
- During port open procedure if autonegotion fails, configuration of
packet processor won't be finished and open procedure exits with error.
- However this won't prevent u-boot network framework from
calling

An eralier commit in this changeset is taken from Marvells repos but was
based on an MVMDIO implementation that never made it into U-Boot. With
this patch the mvpp2 driver switches to use the new MVMDIO driver that is
based on a more universal mdio-uclass implementation.

Since marvell MDIO driver is added, SMI function implementation in
mvpp2 driver can be removed and NETA driver can use marvell MDIO API
directly.
This replacement also fixes 2 old issues:

Currently, there are 2 valid cases for interface, PHY
and mdio relation:
- If an interface has PHY handler, it'll call
mdio_mii_bus_get_from_phy(), which will register
MDIO bus.
- If we want to use fixed-link for an interface,
PHY handle is not defined in the

If the phy doesn't match with any existing u-boot drivers the phy

This commit ports mvpp2 to use the recently introduced Marvell MDIO
(MVMDIO) driver. It removes direct interaction with the SMI & XSMI
busses. This commit is based in part on earlier work by
Ken Ma in Marvell's own downstream repo:

This patchset includes a couple of commits form Marvell's downstream repo
and a change to replace mvpp2's SMI implementation with the new MVMDIO
driver. The mvpp2 change is based partially on Ken Ma's mods against an
earlier (his) version of MVMDIO that never made it to upstream
From: Nevo Hed
Changes to mvpp2.c require the MVMDIO module which in turn uses
DM_MDIO.
