net: phy: Do not double remove phy device ...

This fixes: 80264a8 driver: Call bus->remove instead of driver->remove

On mvebu it happens that:

Upon device shutdown, when iterating through the active device list,
the phy0 device is removed before mdio-mvebu. Then, when the mdio bus
device is removed, the phy0 device is removed again, here:

mdio_bus_remove(on mdio-mvebu)
  mvebu_mdio_remove
    mdiobus_unregister
      unregister_device
        mdio_bus_remove(on phy0)

Fix this by setting the mdio busses phy_map[phy->addr] to NULL when
unregistering the phy device, so that mdiobus_unregister no longer
finds a valid phy_device when iterating over the busses device list.

PCI: fill in bus primary field ...

This was erroneously left uninitialzed as nothing was using it.
The i.MX6 PCI driver needs this to be filled properly to decide
if a config space access is allowed for a specific devfn.

This fixes PCI enumeration on the Gateworks GW54xx board.

mtd: partition: Fix OF partition fixup ...

To get the number of address cells and size cells we have to use
the newly created partition node, not the parent device node. The
parent device node returns the address/size cells of the controller
node, not the partition node.

On an am335x machine this fixes the device tree passed to Linux.
The situation there is:
	...
	gpmc@50000000 {
		...
		#address-cells = <0x2>;
		#size-cells = <0x1>;
		ranges = <0x0 0x0 0x8000000 0x10000000>;
		...
		nand@0,0 {
			reg = <0x0 0x0 0x0>;
			#address-cells = <0x1>;
			#size-cells = <0x1>;
			...
			partition@7 {
				label = "system";
				reg = <0x220000 0x7de0000>;
			};
		};
	};

and without this patch barebox passes three bytes for
partition@7's reg property instead of only two which naturally
confuses Linux and yields to the system partition to start at 0
with a size of 0x220000.

net: Add Intel e1000 driver ...

This adds the Intel e1000 driver from U-Boot. The driver looks in parts
quite similar to the kernel driver, I don't know whether one is derived
from the other or if they both just have the same origin.

Many coding style related issues are fixed, the code is simplified in
several places. All features of the original driver should still be there,
only fiber support is disabled since it's quite unlikely that this is
used in barebox.

The driver has been tested with the i.MX6 PCIe driver and a I210 e1000
device (0x8086:0x1533)
