Luka Perkov 69d323f231 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 008/203] clk: mvebu: add more PCIe clocks for Armada XP
The current revision of the datasheet only mentions the gatable clocks
for the PCIe 0.0, 0.1, 0.2 and 0.3 interfaces, and forgot to mention
the ones for the PCIe 1.0, 1.1, 1.2, 1.3, 2.0 and 3.0
interfaces. After confirmation with Marvell engineers, this patch adds
the missing gatable clocks for those PCIe interfaces.
It also changes the name of the previously existing PCIe gatable
clocks, in order to match the naming using the datasheets.
