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.

Some params are already present in mac_dev. Use them directly instead of
passing them through params.

This member was used to pass the phy node between mac_probe and the
mac-specific initialization function. But now that the phy node is
gotten in the initialization function, this parameter does not serve a
purpose. Remove it, and do the grabbing of the node/grabbing of the phy
in the same place.

There are two ways that GRS can be set: graceful_stop and dtsec_isr. It
is cleared by graceful_start. If it is already set before calling
graceful_stop, then that means that dtsec_isr set it. In that case, we
will not set GRS nor will we clear it (which seems like a bug?). For GTS
the logic is similar, except that there is no one else messing with this
bit (so we will always set and clear it). Simplify the logic by always
setting/clearing GRS/GTS. This is less racy that the previous behavior,
and ensures that we always end up clearing the bits. This can of course
clear GRS while dtsec_isr is waiting, but because we have already done
our own waiting it should be fine.
This is the last user of enum comm_mode, so remove it.

Fix memory allocation for ethernet address hash table.
The code was wrongly allocating an array for eth hash table which
is incorrect because this is the main structure for eth hash table
(struct eth_hash_t) that contains inside a number of elements.

Add the Data Path Acceleration Architecture Frame Manger MAC support.
This patch adds The FMan MAC configuration, initialization and
runtime control routines.
This patch contains support for these types of MACs:
- dTSEC: Three speed Ethernet controller (10/100/1000 Mbps)
- tGEC: 10G Ethernet controller (10 Gbps)
- mEMAC: Multi-rate Ethernet MAC (10/100/1000/10000 Mbps)
Different FMan revisions have different type and number of MACs.
