This converts DPAA to phylink. All macs are converted. This should work
with no device tree modifications (including those made in this series),
except for QSGMII (as noted previously).

The mEMAC configuration is one of the tricker areas. I have tried to
capture all the restrictions across the various models. Most of the time,
we assume that if the serdes supports a mode or the phy-interface-mode
specifies it, then we support it. The only place we can't do this is
(RG)MII, since there's no serdes. In that case, we rely on a (new)
devicetree property.  There are also several cases where half-duplex is
broken. Unfortunately, only a single compatible is used for the MAC, so we
have to use the board compatible instead.

The 10GEC conversion is very straightforward, since it only supports XAUI.
There is generally nothing to configure.

The dTSEC conversion is broadly similar to mEMAC, but is simpler because we
don't support configuring the SerDes (though this can be easily added) and
we don't have multiple PCSs. From what I can tell, there's nothing
different in the driver or documentation between SGMII and 1000BASE-X
except for the advertising. Similarly, I couldn't find anything about
2500BASE-X. In both cases, I treat them like SGMII. These modes aren't used
by any in-tree boards. Similarly, despite being mentioned in the driver, I
couldn't find any documented SoCs which supported QSGMII.  I have left it
unimplemented for now.

10GEC and dTSEC have not been tested at all. I would greatly appreciate if
someone could try them out.

This has been tested on an LS1046ARDB.

With managed=phy, I was unable to get the interfaces to come up at all,
hence the default to in-band.

(no changes since v3)

Changes in v3:
- Remove _return label from memac_initialization in favor of returning
  directly
- Fix grabbing the default PCS not checking for -ENODATA from
  of_property_match_string
- Set DTSEC_ECNTRL_R100M in dtsec_link_up instead of dtsec_mac_config
- Remove rmii/mii properties

Changes in v2:
- Remove unused variable slow_10g_if
- Restrict valid link modes based on the phy interface. This is easier
  to set up, and mostly captures what I intended to do the first time.
  We now have a custom validate which restricts half-duplex for some SoCs
  for RGMII, but generally just uses the default phylink validate.
- Configure the SerDes in enable/disable
- Properly implement all ethtool ops and ioctls. These were mostly
  stubbed out just enough to compile last time.
- Convert 10GEC and dTSEC as well
