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 141/203] mtd: nand: pxa3xx: Use waitfunc() to wait for the
+ device to be ready
+
+In pxa3xx_nand_sensing() instead of simply using info->is_ready
+after issuing a command, the correct way of checking is to wait
+for the device to be ready through the chip's waitfunc().
