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 155/203] mtd: nand: pxa3xx: Use info->use_dma to release DMA
+ resources
+
+After the driver allocates all DMA resources, it sets "info->use_dma".
+Therefore, we need to check that variable to decide which resources
+needs to be freed, instead of the global use_dma variable.
+
+Without this change, when the device probe fails, the driver will try
+to release unallocated DMA resources, with nasty results.
