ARM: Berlin: Ethernet support

This series introduce support for the Ethernet controller on Berlin SoCs,
using the existing pxa168 Ethernet driver. In order to do this, DT
support is added to the driver alongside some other modifications and
fixes.

This has been tested on a Berlin BG2Q DMP board.

Changes since v5:
	- fixed the build when building the driver as a module

Changes since v4:
        - removed the phy-addr property and added a phy subnode
        - added COMPILE_TEST for the pxa168_eth driver

Changes since v3:
        - moved the addition of pxa168_eth_get_mac_address() to the patch
          using it first

Changes since v2:
        - reworked how the MAC address is configured
        - made the clock anonymous

Changes since v1:
        - removed custom Berlin Ethernet driver
        - used the pxa168 Ethernet driver instead
        - made modifications to the pxa168 driver (DT support, fixes)

mlx4_core driver updates

A series from Jack and Co of low-level fixes for the mlx4_core driver
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

ConnectX2 HCAs have max_mtu=4k and max_vl=8 vls. However, if you specify
a 4K mtu, the max_vl supported for 4K is 4 vls. The driver at startup
attempts to set a 4K mtu using the max_vl value obtained from QUERY_PORT.

Since the max_vl value is 8 vls (which is supported up to 2K mtu size),
the first attempt to set the mtl/vl port value will fail, generating
the following error message in the log:

  mlx4_core 0000:06:00.0: command 0xc failed: fw status = 0x40

The driver then tries again, using mtu=4k, vls=4, and this succeeds.

Since we do not want to have this error message always displayed at driver
start when there are ConnectX2 HCAs on the host, we deprecate the error
message for this specific command/input_modifier/opcode_modifier/fw-status
to be debug.

In the new flow, we separate the pci initialization and teardown
from the initialization and teardown of the other resources.

__mlx4_init_one handles the pci resources initialization. It then
calls mlx4_load_one to initialize the remainder of the resources.

When removing a device, mlx4_remove_one is invoked. However, now
mlx4_remove_one calls mlx4_unload_one to free all the resources except the pci
resources. When mlx4_unload_one returns, mlx4_remove_one then frees the
pci resources.

The above separation will allow us to implement 'reset flow' in the future.
It will also enable more EQs for VFs and is a pre-step to the modern API to
enable/disable SRIOV.

Also added nvfs; an integer array of size MLX4_MAX_PORTS + 1; to the mlx4_dev
struct. This new field is used to avoid parsing the num_vfs module parameter
each time the mlx4_restart_one is called.
