This patch activates every USB port provided by each SoC.
Except for Armada XP Openblocks AX3-4 board,
where we enable only the first two USB ports
until we have more information on the third one usage.

The OpenBlocks AX3-4 board has one software-controlled button on the
front side, labeled "INIT", so we add minimal support for this button
in the kernel.

This patch enables SATA support on the OpenBlocks AX3-4. It has one
internal SATA port, and an external eSATA port.

The OpenBlocks AX3-4 has a Seiko Instruments S-35390A as the RTC
controller.  This patch enables this RTC device in the OpenBlocks
AX3-4 Device Tree.

The OpenBlocks AX3-4 board, based on the Armada XP SoC, has an I2C
bus. This patch enables this bus and sets the clock frequency of the
bus.

The mvneta driver for the Marvell Armada 370/XP Ethernet devices has
gained proper clock framework integration, and the corresponding
Device Tree nodes now have a correct 'clocks' pointer.

The 'clock-frequency' properties in the various .dts files for Armada
370/XP boards have therefore become useless.

The PlatHome OpenBlocks AX3-4 platform has 4 Ethernet ports, connected
to a single quad-port PHY through SGMII.

This platform, available in Japan from PlatHome, has a dual-core
Armada XP, the MV78260. For now, only the two serial ports and the
three front LEDs are supported. Support for SMP, network, SATA, USB
and other peripherals will be added as drivers for them become
available for Armada XP in mainline.

This is 3.8 material.

Changes since v2:

 * Renamed the .dts file to armada-xp-openblocks-ax3-4.dts

 * Removed the compatible string from armada-370-xp.c (which now only
   lists the common SoC compatible string)

Changes since v1:

 * Renamed the board to OpenBlocks AX3-4, since there is a variant
   called AX3-2 which has less RAM, and no mini PCIe port. Requested
   by Andrew Lunn.

 * Fix the amount of memory to 3 GB. In fact, the board has 1 GB
   soldered, and 2 GB in a SODIMM slot (which is therefore
   removable). But as the board is delivered as is, we'll assume it
   has 3 GB of memory by default.
