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 164/203] ARM: mvebu: fix register length for Armada XP PMSU
+
+The per-CPU PMSU registers documented in the datasheet start at
+0x22100 and the last register for CPU3 is at 0x22428. However, the DT
+informations use <0x22100 0x430>, which makes the region end at
+0x22530 and not 0x22430.
+
+Moreover, looking at the datasheet, we can see that the registers for
+CPU0 start at 0x22100, for CPU1 at 0x22200, for CPU2 at 0x22300 and
+for CPU3 at 0x22400. It seems clear that 0x100 bytes of registers have
+been used per CPU.
+
+Therefore, this commit reduces the length of the PMSU per-CPU register
+area from the incorrect 0x430 bytes to a more logical 0x400 bytes.
