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 201/203] PCI: mvebu: increment nports only for registered
+ ports
+
+The number of ports is probed by counting the number of available child nodes.
+Later on, the registration of a port can fail and cause a mismatch between
+the ->nports counter and registered ports. This patch modifies the counting
+strategy, to make ->nports represent the number of registered ports instead
+of the number of available childs.
