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 136/203] mtd: nand: pxa3xx: Use chip->cmdfunc instead of the
+ internal
+
+Whenever possible, it's always better to use the generic chip->cmdfunc
+instead of the internal pxa3xx_nand_cmdfunc().
+In this particular case, this will allow to have multiple cmdfunc()
+implementations for different SoC variants.
