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 095/203] mtd: nand: fix memory leak in ONFI extended parameter
+ page
+
+This fixes a memory leak in the ONFI support code for detecting the
+required ECC levels from this commit:
+
+  commit 6dcbe0cdd83fb5f77be4f44c9e06c535281c375a
+  Author: Huang Shijie <b32955@freescale.com>
+  Date:   Wed May 22 10:28:27 2013 +0800
+
+      mtd: get the ECC info from the Extended Parameter Page
+
+In the success case, we never freed the 'ep' buffer.
+
+Also, this fixes an oversight in the same commit where we (harmlessly)
+freed the NULL pointer.
