mvebu: backport mainline patches from kernel 3.13

This is a backport of the patches accepted to the Linux mainline related to
mvebu SoC (Armada XP and Armada 370) between Linux v3.12, and Linux v3.13.
This work mainly covers:

* Finishes work for sharing the pxa nand driver(drivers/mtd/nand/pxa3xx_nand.c)
  between the PXA family, and the Armada family.
* timer initialization update, and access function for the Armada family.
* Generic IRQ handling backporting.
* Some bug fixes.

+Subject: [PATCH 178/203] of: clean-up ifdefs in of_irq.h
+
+Much of of_irq.h is needlessly ifdef'ed. Clean this up and minimize the
+amount ifdef'ed code. This fixes some  build warnings when CONFIG_OF
+is not enabled (seen on i386 and x86_64):
+
+include/linux/of_irq.h:82:7: warning: 'struct device_node' declared inside parameter list [enabled by default]
+include/linux/of_irq.h:82:7: warning: its scope is only this definition or declaration, which is probably not what you want [enabled by default]
+include/linux/of_irq.h:87:47: warning: 'struct device_node' declared inside parameter list [enabled by default]
+
+Compile tested on i386, sparc and arm.
