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 194/203] clocksource: armada-370-xp: Add detailed clock
+ requirements in devicetree binding
+
+Specifies the required clock inputs for each supported compatible.
+Armada 370 requires a single clock phandle, and Armada XP requires
+two clock phandles with clock-names "nbclk" and "fixed".
