Luka Perkov 69d323f231 mvebu: backport mainline patches from kernel 3.11
This is a backport of the patches accepted to the Linux mainline related to
mvebu SoC (Armada XP and Armada 370) between Linux v3.10, and Linux v3.11.
This work mainly covers:

* Enabling USB storage, and PCI to mvebu_defconfig.
* Add support for NOR flash.
* Some PCI device tree related updates, and bus parsing.
* Adding Armada XP & 370 PCI driver, and update some clock gating
  specifics.
* Introduce Marvell EBU Device Bus driver.
* Enaling USB in the armada*.dts.
* Enabling, and updating the mvebu-mbus.
* Some SATA and Ethernet related fixes.

Subject: [PATCH 027/203] arm: mvebu: remove hardcoded static I/O mapping
Now that we have removed the need of the static I/O mapping for early
initialization reasons, and fixed the registers area length that were
broken, we can get rid of the static I/O mapping. Only the earlyprintk
mapping needs to be set up, using the debug_ll_io_init() helper
function.
