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 060/203] ARM: kirkwood: Split DT and legacy MBus
+ initialization
+
+This commit replaces the legacy MBus initialization with the new
+DT-based in Kirkwood. For boards that are not yet converted to DT,
+we keep the legacy initialization.
