Luka Perkov 3af779eb17 mvebu: backport mainline patches from kernel 3.12
This is a backport of the patches accepted to the Linux mainline related to
mvebu SoC (Armada XP and Armada 370) between Linux v3.11, and Linux v3.12.
This work mainly covers:

* Ground work for sharing the pxa nand driver(drivers/mtd/nand/pxa3xx_nand.c)
  between the PXA family,and the Armada family.
* Further updates to the mvebu MBus.
* Work and ground work for enabling MSI on the Armada family.
* some phy / mdio bus initialization related work.
* Device tree binding documentation update.

Subject: [PATCH 088/203] ARM: mvebu: re-enable PCIe on Armada 370 DB
Commit 14fd8ed0a7fd19913 ("ARM: mvebu: Relocate Armada 370/XP PCIe
device tree nodes") relocated the PCIe controller DT nodes one level
up in the Device Tree, to reflect a more correct representation of the
hardware introduced by the mvebu-mbus Device Tree binding.
However, while most of the boards were properly adjusted accordingly,
the Armada 370 DB board was left unchanged, and therefore, PCIe is
seen as not enabled on this board. This patch fixes that by moving the
PCIe controller node one level-up in armada-370-db.dts.
