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.
