This time around, the cleanup branch contains mostly code removal. A number
of board files for at91, imx and msm have become obsolete because of the
DT conversion and are now ready to be removed. The OMAP platform has
traditionally had its own DMA engine abstraction and as this is being
phased out, a lot of the original code is now unused and can be removed
as well.
S3C24xx can be simplified now that the restart code is a proper device
driver.
Finally, a number of cleanups in shmobile are done to prepare for
the addition of new code in other branches.

A large part of the arm-soc patches are nowadays DT changes, adding support
for new SoCs, boards and devices without changing kernel source. The plan
is still to move the devicetree files out of the kernel tree and reduce
the amount of churn going on here, but we keep finding reasons to delay
doing that.
Changes are really all over the place, with little sticking out particularly.
We have contributions from a total of 116 people in this branch.
Unfortunately, the size of this branch also causes a significant number
of conflicts at the moment, typically when subsystem maintainers merge
patches that change the driver at the same time as the dts files. In
most cases this could be avoided because the dts changes are supposed
to be compatible in both ways, and we are asking everyone to send ARM
dts changes through our tree only.

As we currently need to support a mix of legacy platform data and
device tree intialized data, let's make sure things keep working
for the TWL GPIOs.
Mostly the issue is caused by the fact that DSS does not yet have
device tree bindings, so we need to rely on the TWL GPIO callback
for setting up things like LCD backlight for some boards.
As of_platform_populate() for the TWL GPIO is called by twl-core
after the I2C bus has been initialized, we cannot pass the auxdata
table from the board init code to twl-core like we used to with
just legacy platform data.
So let's use the omap_device bus hook to patch in the platform
data for TWL GPIO until we have sorted out the issues with the
TWL GPIOs and device tree bindings.
The other option was be to initialize twl core using legacy
platform data, which seems like a step backwards as we're moving
to device tree only initialization. And we really don't want to
add custom configuration functions to the TWL GPIO driver either
for this.
