Add compatible string for MPC5125 FEC. The FEC on MPC5125 additionally
supports RMII PHY interface. Configure controller/PHY interface type
according to the optional phy-connection-type property in the ethernet
node. This property should be either "rmii" or "mii".

The __netif_subqueue_stopped() just does the following:
struct netdev_queue *txq = netdev_get_tx_queue(dev, queue_index);
return netif_tx_queue_stopped(txq);
and since we already have the txq in scope, we can just call that
directly in this case.

Add support for byte queue limits (BQL), based on the similar
modifications made to intel/igb/igb_main.c from Eric Dumazet
in commit bdbc063129
"igb: Add support for byte queue limits."

gfar_clean_tx_ring, since it is now used often enough to warrant it,

Factor out the the existing allocation and free operations
so that they can be used individually.
This is to improve code readability, and also to prepare for
possible future changes like better error recovery and more
dynamic configuration (e.g on-the-fly resizing of the rings).
This change represents a straight up relocation of the existing
code into separate routines without changing any of the contained
code itself. Local variables are relocated as necessary.

Commit "391420f7: fec: use an unique MDIO bus name" first modified
the MDIO bus name to include the platform name, then in commit
"a7ed07d5: net: fec: correct phy_name buffer length when init phy_name"
the PHY name formatting was fixed in the case the PHY matches a PHY
driver.
The FEC driver however, also handles the case where we want to attach
to the fixed MDIO bus name, which was previously named "0", and now
"fixed-0". Change the PHY formatting logic to account for that.

When TX time stamping for PTP messages is enabled on a socket, a time
stamp is returned on the socket error queue to the user space application
after the frame was transmitted. The transmitted frame is also returned on
the error queue so that an application knows to which frame the time stamp
belongs.
In the current implementation the TxFCB is immediately followed by the
frame. Since the eTSEC inserts the TX time stamp 8 bytes after the TxFCB,
parts of the frame have been overwritten and an invalid frame was returned
on the socket error queue.
This patch fixes the described problem by adding additional 16 padding
bytes between the TxFCB and the frame for all messages sent from a time
stamping enabled socket (other sockets are not affected).

When there is not enough headroom in the skb a private copy will be made.
However, the private copy had no reference to the socket and consequently
no time stamp could be queued on the socket error queue during the
skb_tstamp_tx function. This patch fixes this issue by also stealing the
sock reference from the original skb after making the private copy.

If one only selects mx23-based boards, compile fails:

drivers/net/ethernet/freescale/fec.c:411:2: error: 'FEC_HASH_TABLE_LOW' undeclared (first use in this function)
This is because fec.h uses CONFIG_SOC_IMX28 to determine the register
layout of the core which makes sense since the MX23 does not have a fec.
However, Kconfig uses the broader ARCH_MXS symbol and this way even
makes the fec-driver default for MX23. Adapt Kconfig to use the more
precise SOC_IMX28 as well.

On extensive NFS boots on a mx6qsabrelite board it was noted that "FEC: MDIO read timeout" were occuring,
which caused failure on loading the FEC driver.
The original FEC_MII_TIMEOUT was set to 1 ms, which is too low when passed to the usecs_to_jiffies macro.
On ARM one jiffy is 10ms, so use a timeout of 30ms, which corresponds to 3 jiffies.
After running extensive NFS boots, the MDIO timeouts do not occur anymore with this change.

The .remove code is broken in several ways.
- mdiobus_unregister() is called twice for the same object in case of dual FEC
- phy_disconnect() is being called when the PHY is already disconnected
- the requested IRQ(s) are not freed
- fec_stop() is being called with the inteface already stopped
All of those lead to kernel crashes if the remove function is actually used.

The pdev->id is used in several places for different purpose. All
these uses assume it's always the id of fec device which is >= 0.
However this is only true for non-DT case. When DT plays, pdev->id
is always -1, which will break these pdev->id users.
Instead of fixing all these users one by one, this patch introduces
a new member 'dev_id' to 'struct fec_enet_private' for holding the
correct fec device id, and replaces all the existing uses of pdev->id
with this dev_id.
