Instead of directly accessing the fault registers, use proper accessors
so the core code can be shared.

On 32bit ARM, unsigned long is guaranteed to be a 32bit quantity.
On 64bit ARM, it is a 64bit quantity.
In order to be able to share code between the two architectures,
convert the registers to be unsigned long, so the core code can
be oblivious of the change.

Pull ARM SoC mvebu platform changes from Olof Johansson:
"This series contains changes for the Marvell EBU platforms (mvebu,
orion, kirkwood, dove) that were not part of the first set of pull
requests because of dependencies on the MMC tree, and being submitted
a little late.
Notable changes are:
- More devices get moved out of board files into device tree
descriptions. The remaining devices listed in there have patches
that will get sent for 3.10, after which we can remove a lot of the
board files entirely. We are doing the pinctrl and mmc drivers
here, ethernet and PCI still remain.
- SMP support for mvebu is improved with support for the local
interrupt controller.
- The Guruplug board file gets replaced with a DT description.
Unfortunately, the dependency on the MMC tree turned out to be a much
larger problem than expected, when the MMC maintainer rebased the
patches in his tree that all of the patches in this branch are based
on, which caused merge conflicts between the new and old versions of
those patches.
To work around the merge conflicts, this branch rebases all patches on
top of the respective MMC patches that did get merged into 3.9. The
patches are all identical to the versions that were part of
linux-next, but have a new commit date."

Pull ARM SoC i.MX DT changes from Olof Johansson:
"This branch contains of devicetree changes for the Freescale i.MX
platform.
The base patch of the branch changes the format of the dts files to a
slightly different format that makes it easier to do derivative board
definitions, but it also introduces a lot of churn in the process
since every line of the file is touched.
On top of that are a handful of the regular changes; enabling more
boards as DT-based instead of legacy board files (mx25pdk), enabling
another driver for devicetree and thus adding bindings (onewire), etc.
I'm not happy about the churn, and will likely not take it for other
platforms in the future."

Note that the Armada XP SPI register length is 0x50 bytes,
while Armada 370 SPI register length is 0x28 bytes,
so we choose the smaller of the two.

The Armada XP DB evaluation board has one SD card slot, directly
connected to the SDIO IP of the SoC, so we add a device tree
description for it.
However, in the default configuration of the board, the SD card slot
is not usable: the connector plugged into CON40 must be changed
against a different one, provided with the board by the
manufacturer. Since such a manual modification of the hardware is
needed, we did not enable the SDIO interface by default, and left it
to the board user to modify the Device Tree if needed. Since this
board is really only an evaluation board for developers and not a
final product, it is not too bad.

The SDIO interface is only available on pins MPP30/31/32/33/34/35 on
the various Armada XP variants, so we provide a pin muxing option for
this in the Armada XP .dtsi files.
Even though those muxing options are the same for MV78230, MV78260 and
MV78460, we keep them in each .dtsi file, because the number of pins,
and therefore the declaration of the pinctrl node, is different for
each SoC variant.
