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 190/203] of/irq: Fix bug in interrupt parsing refactor.
+
+Commit 2361613206e6, "of/irq: Refactor interrupt-map parsing" introduced
+a bug. The irq parsing will fail for some nodes that don't have a reg
+property. It is fixed by deferring the check for reg until it is
+actually needed. Also adjust the testcase data to catch the bug.
