mvebu: backport mainline patches from kernel 3.11

This is a backport of the patches accepted to the Linux mainline related to
mvebu SoC (Armada XP and Armada 370) between Linux v3.10, and Linux v3.11.
This work mainly covers:

* Enabling USB storage, and PCI to mvebu_defconfig.
* Add support for NOR flash.
* Some PCI device tree related updates, and bus parsing.
* Adding Armada XP & 370 PCI driver, and update some clock gating
  specifics.
* Introduce Marvell EBU Device Bus driver.
* Enaling USB in the armada*.dts.
* Enabling, and updating the mvebu-mbus.
* Some SATA and Ethernet related fixes.

+Subject: [PATCH 037/203] memory: mvebu-devbus: Remove address decoding window
+ workaround
+
+Now that mbus device tree binding has been introduced, remove the address
+decoding window management from this driver.
+A suitable 'ranges' entry should be added to the devbus-compatible node in
+the device tree, as described by the mbus binding documentation.
