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 097/203] ARM: mvebu: Add a 2 GHz fixed-clock Armada 370/XP
Armada 370/XP SoCs have a 2 GHz fixed PLL that is used to feed
other clocks. This commit adds a DT representation of this clock
through a fixed-clock compatible node.
