net: Add Freescale FMan ethernet support ...

This adds ethernet support for the Freecale Layerscape SoCs. The
architecture in these SoCs is called "Data Path Acceleration
Architecture" (DPAA). It is comprised of:

- The Queue Manager (QMan)
- Buffer Manager (BMan)
- Frame Manager (FMan)
- Multirate Ethernet Media Access Controller (mEMAC)

The code is based on the corresponding U-Boot driver enriched with
device tree parsing and proper device driver support.

Tested on LS1046a, should work on other SoCs aswell with some minor
quirks. SerDes support has been removed for now.

net: ethernet: cpsw: cpsw-phy-sel: Use phandle for phy sel ...

With the usage of the interconnect target module hierarchy in device tree the
cpsw-phy-sel node moved to the system control module. An phandle has
been added instead to the device tree include.

Try to use the cpsw-phy-sel phandle first then fall back looking for the
cpsw-phy-sel child.

This patch is based on the upstream kernel patch:

net: phy: micrel: backport ksz9031 125MHz ref-clk workaround ...

This patch backports linux commit e1b505a60366 ("net: phy: micrel: add
125MHz reference clock workaround").

8<--------------------- The original commit message -------------------

net: phy: micrel: add 125MHz reference clock workaround

The micrel KSZ9031 phy has a optional clock pin (CLK125_NDO) which can be
used as reference clock for the MAC unit. The clock signal must meet the
RGMII requirements to ensure the correct data transmission between the
MAC and the PHY. The KSZ9031 phy does not fulfill the duty cycle
requirement if the phy is configured as slave. For a complete
describtion look at the errata sheets: DS80000691D or DS80000692D.

The errata sheet recommends to force the phy into master mode whenever
there is a 1000Base-T link-up as work around. Only set the
"micrel,force-master" property if you use the phy reference clock provided
by CLK125_NDO pin as MAC reference clock in your application.

Attenation, this workaround is only usable if the link partner can
be configured to slave mode for 1000Base-T.

net: fec_imx: skip fec_halt if the FEC wasn't started ...

If the FEC driver is enabled, but the ethernet device was never
opened due to booting from another source the wait for graceful
transmit stop will always fail. This introduces an unnecessary
boot delay and prints a distracting warning.

As there is no point in trying to shut down the FEC if it was
never started, just skip all of fec_halt in that case.
